Answer 1

The right option is; D. Offspring

This behavior has developed due to natural selection, since an effective dance helps to attract a mate and produce offspring.

Offspring is the new individual organisms (product) produced from the reproductive processes of living organisms. Offspring can be produced through asexual reproduction by a single organism or through sexual reproduction which involves sexual interaction of two organisms. In sexual reproduction, offspring that are genetically identical to the two parental organisms are produced. Offspring are made up of several characteristics, and components that are definite and perfect in what they contain, and in their expression.
