As per Sheldon's view Ectomorphs are:

Question

Accepted Answer

The correct option is (2):
According to the psychological and physiological theory of somatotyping developed by Dr. William Herbert Sheldon, there are three primary body types: Ectomorph, Mesomorph, and Endomorph. The Ectomorph is characterized by a linear and fragile build, representing minimal mass in comparison to surface area. These individuals typically possess a delicate bone structure, minimal body fat, and slender limbs. Their physical structure is defined by leanness and a narrow frame, making "Thin and slender frame" the most accurate descriptor of the Ectomorphic somatotype. Ectomorphs generally have a fast metabolism and find it difficult to gain weight, whether muscle or fat, and are often perceived as stringy or delicate in appearance.

The incorrect option is (1):
The description "Bulky and stocky body" refers to the Endomorph somatotype in Sheldon's classification system. Endomorphs are characterized by a relatively high proportion of body fat and a round, soft, and stocky appearance. They typically have a large bone structure and limbs that are shorter and thicker, indicating a dominance of the endoderm from which the digestive viscera develop. This body type has difficulty losing fat and is often associated with a higher capacity for storing energy. Therefore, this option represents the opposite end of the spectrum from an Ectomorph.

The incorrect option is (3):
The phrase "Muscular and V shape body" is the definitive characteristic of the Mesomorph somatotype. Mesomorphs exhibit a dominance of the mesoderm, from which muscle and bone develop. This leads to a naturally athletic, hard, and triangular body structure, often described as having a broad chest, a narrow waist, and dense muscle tissue. This physical build is associated with high levels of strength and a natural predisposition to build muscle mass. The Mesomorph represents the balanced, athletic ideal, distinctly differentiating it from the thin frame of the Ectomorph.

The incorrect option is (4):
The description "Active and Attractive" is a general, subjective assessment of personality or appearance and does not define a body *shape* according to Sheldon's somatotypes. Sheldon's system primarily classifies the physical *structure* or morphology of the body, which is what the question is asking for. While some psychological research links somatotypes to temperament (Ectomorphs are linked to Cerebrotonia, for instance), "Active and Attractive" is too vague and non-anatomical. All body types can be active and considered attractive, rendering this option irrelevant to the morphological classification of Ectomorphs.
