Answer 1

Answer: (A)

Insects have three pairs of legs and two pairs of wings while spiders have four pairs of legs and no wings.

Insects have three pairs of legs (six legs) while spiders have four pairs of legs (eight legs). Insects have two pairs of wings that are found in the second and third thoracic segments, but spiders do not have wings.

So, the correct option is 'insects have three pairs of legs and two pairs of wings while spiders have four pairs of legs and no wings.'
