Solution

The correct option is A Number of students having height in range of 160-174 cm is 5
The number of students having height in the range of 160 - 164 cm = 2

The number of students having height in the range of 165 - 169 cm = 1

The number of students having height in the range of 170 - 174 cm = 2
$∴$ the number of students having height in range of 160-174 cm = 2 + 1 + 2 = 5.
