Q. The electrical size of antenna is increased by antenna array to avoid size lobes compared to single antenna.

(A) true
(B) false
(C) ---
(D) ---
Correct : Option (A)

Explanation: 
 increasing the dimensions of antennas may lead to the appearance of the side lobes. so by placing a group of antennas together the electrical size of antenna can be increased. with the antenna arrays, directivity and gain increases and beam width decreases.
