i) Since the number of girls is our frequency column, we can see that the highest frequency is 18, which corresponds to the interval 145 - 150. So, the correct option is (i)
ii) The width of the class is the upper interval - lower interval or the class size. In our case, if we take any interval, our class size will be 5.
Like, 140-135 = 5
145-140 =5 and so on
So, the correct option is (iii)
iii) To calculate the no. of students with height 150cm and below, we add all the frequency of intervals upto 150.
So, No. of students upto height 150 cm and below = 4+7+18 = 29
