Correct Answer

✅ Option a — 3.2

All Options:

A3.2
B2.4
C3.5
D3.6

Detailed Solution & Explanation

**Step 1: Recall the relationship AM × HM = GM².**

\text{AM} \times \text{HM} = \text{GM}^2

**Step 2: Substitute values.** - AM = 5, GM = 4

5 \times \text{HM} = 4^2 = 16

\text{HM} = \frac{16}{5} = 3.2

Hence, **Option A** is the correct answer.
