Correct Answer

✅ Option c — 4.0

All Options:

A4.4
B4.2
C4.0
D3.8

Detailed Solution & Explanation

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

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

**Step 2: Substitute values.** - AM = 5, HM = 3.2

\text{GM}^2 = 5 \times 3.2 = 16

\text{GM} = \sqrt{16} = 4.0

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