Show answer and explanation

Correct answer: (D) (i), (ii) and (iii) only

Explanation

According to this chart, Butterfly is placed inside the Bird sector, the Tiger sector exceeds the Red-ant sector, and the Reptile sector is partitioned into Snake and Crocodile. Thus statements(i),(ii),(iii)are supported, **D**. A population chart does not establish physical animal size, so(iv)is not inferred. The Butterfly classification is a source-chart error, not correct zoology.
