Best answer
The correct option is (a) the number of lobes also increase

For explanation: An antenna is basically a transducer that converts radio frequency fields into alternating current or vice versa. They can be used for both transmission and reception of radio signals. If the length of a long wire antenna is increased then the number of lobes also increases. The reception capability of an antenna also depends on it’s length.
