Solution

The correct option is A 64
Every generation of a family tree has double the number of members in the previous generation.

Starting from the current generation (1 member),
First generation =1×2=2 members

Second generation =2×2=4 members

Third generation =4×2=8 members

Fourth generation =8×2=16 members

Fifth generation =16×2=32 members

Sixth generation =32×2=64 members
