Answer 1

The correct option is B Have structures that need not indicate a unity of plan

Structures that indicate the unity of plan indicates common ancestry. While for adapting to the same way of life, organisms require structures with a similar function instead of the unity of plan of structures.

So, the correct option is 'Have structures that need not indicate a unity of plan'.
