Solution

The correct option is B Its development
Lamarck illustrated his theory using the example of the evolution of giraffes. They had short-necked ancestors that had tried all their lives to reach for the juicy leaves of trees. By constantly stretching their necks, they grew longer and longer, a property which they passed on to their offspring. The long neck of the giraffe is said to have come into existence in this manner over generations. So, according to Lamarck intense use of an organ results in its development.
