b. 1-A, 2-C, 3-B, 4-D
c. 1-B, 2-D, 3-A, 4-C
d. 1-0, 2-A, 3-C, 4-B​

Answer 1

sorry I can't understand what you are saying

Answer 2

Answer:

The answer is b) 1-A,2-C,3-B,4-D.

Explanation :-

The POLE is midpoint of reflecting surface of a Mirror.

PRINCIPLE AXIS is imaginary line that passes through pole and center of curvature.

RADIUS OF CURVARURE is the fadius of hollow sphere shich reflecting surface forms a part.

And APERTURE is width of mirror where reflection takes place.

SO the correct answer is b) 1-A,2-C,3-B,4-D.

I hope it helps you !!

Thank you
