The correct option is A 2
Arranging the heights of 12 boys in ascending order we get
$141, 142, 143, 143, 144, 144, 145, 145, 147, 147, 149, 151$

The number of times a particular value of data occurs is known as frequency.
Here, we see there are 2 boys with height 143 cm.
Therefore, the frequency of boys with a height of 143 cm is 2.
