Let A and B are two devices used to play video games. In A there is provision of a handle on a base and buttons for pressing /revolving, while video games are played using B holding it in both the hands and moving it in the air this or that side. Most suitable names for A and B in order are:

Question

Accepted Answer

The correct option is (1):
The correct option is (1): Joy-Stick, Game Pad. The question requires you to match the physical descriptions of two video game controllers, A and B, to the most suitable names. Device A is described as having "a handle on a base and buttons for pressing /revolving." This configuration is the definitive characteristic of a **Joy-Stick**, a classic input device where a vertical lever pivots on a stand for directional control. Device B is described as being played by "holding it in both the hands and moving it in the air this or that side." A **Game Pad** is the primary handheld controller designed to be held in two hands, accommodating both the "holding it in both the hands" criterion. Furthermore, modern Game Pads often incorporate gyroscopic or accelerometer technology, allowing them to also function as motion controllers that are "moved in the air." Therefore, Joy-Stick for A and Game Pad for B is the most appropriate pairing.

The incorrect option is (2):
This option proposes **Light Pen** for device A and **Joy-Stick** for device B. A **Light Pen** is an input device used to select objects or draw on a display screen, and it does not feature a "handle on a base and buttons for pressing/revolving" as described for A. The Joy-Stick, which accurately describes device A, is incorrectly assigned to device B. Device B is a handheld controller moved in the air, which is the opposite of the stationary, base-mounted nature of a Joy-Stick. Thus, both parts of this option fail to match the descriptions.

The incorrect option is (3):
This option suggests **Game Pad** for device A and **Track Ball** for device B. Device A is distinctly defined by having a "handle on a base," which contradicts the handheld, two-sided control design of a Game Pad. For device B, a **Track Ball** is a stationary input device where the user rolls a ball within a housing to move a cursor, which directly opposes the description of a controller that is held and "moving it in the air this or that side." Because a Track Ball must remain on a flat surface to function, this association is fundamentally incorrect.

The incorrect option is (4):
This option reverses the correct pairing by suggesting **Game Pad** for A and **Joy-Stick** for B. The physical description of device A is a "handle on a base," which identifies it as a Joy-Stick. Conversely, device B is a handheld device played by "holding it in both the hands," which is the quintessential design of a Game Pad. This option swaps the essential features and names of the two different devices, making it logically unsound.
