Answer 1

Homologous organs are the organs which have similar structure and different function and have the same developmental origin.

Both the thorns of bougainvillea and tendrils of Cucurbita origin from the stem and are modified from the auxiliary buds but their functions are different. Hence they are homologous organs.

Hence Thorns of Bougainvillea and tendril of Cucurbita are not analogous organs.

So, the answer is 4
