Solution

The correct option is A Scape
The base of the antenna is connected to the edge of the socket by an articulatory membrane. This permits free movement of antennae. The basal segment is called scape. It is conspicuously larger than succeeding segments. The second antennal segment is called pedicle whcih immediately follow the scape.
So the correct answer is "Scape".
