10x eyepiece with a 10x objective
10x eyepiece with a 100x objective
5x eyepiece with a 25x objective

Explanation:

Step1: Recall magnification formula

Total magnification \( M = \text{eyepiece magnification} \times \text{objective magnification} \)

Step2: Check each option

• Option 1: \( 15 \times 40 = 600 \)
• Option 2: \( 10 \times 10 = 100 \)
• Option 3: \( 10 \times 100 = 1000 \)
• Option 4: \( 5 \times 25 = 125 \)

Answer:

15X eyepiece with a 40X objective
