Consider the following statements :
(a) The distance between two latitudes is approximately 111 km.
(b) There are 180 parallels including equator.
(c) All meridians converge at poles.
Choose the correct answer:

Question

Accepted Answer

Option 2, "(a) and (c) are correct," is the correct answer because:

*   **(a) The distance between two latitudes is approximately 111 km:** This statement is factually correct. The Earth's circumference is approximately 40,075 km. Dividing this by 360 degrees (the total degrees in a circle) gives approximately 111 km per degree of latitude. While the exact distance varies slightly due to the Earth's oblate spheroid shape, 111 km is a widely accepted and accurate approximation.

*   **(c) All meridians converge at poles:** This statement is also factually correct. Meridians are lines of longitude that run from the North Pole to the South Pole. By definition, they all meet at the poles.

Now, let's explain why the other options are incorrect:

*   **Option 1: Only (b) is correct.** This is incorrect because statement (a) and (c) are also correct as explained above.

*   **Option 3: (a) and (b) are correct.** This is incorrect because while statement (a) is correct, statement (b) is not entirely accurate. There are 181 parallels (0 to 90 degrees North and 0 to 90 degrees South, plus the equator). The question states "180 parallels including equator" which is incorrect.

*   **Option 4: (a), (b) and (c) are correct.** This is incorrect because statement (b) is not entirely accurate. There are 181 parallels (0 to 90 degrees North and 0 to 90 degrees South, plus the equator). The question states "180 parallels including equator" which is incorrect.

Therefore, only Option 2 accurately identifies the correct statements.
