B.5 inches × 6 inches

C.7 inches × 10.5 inches

D.8 inches × 9 inches

Answer 1

the answer is D
Both sides get enlarged 2 by 4 and 3 by 3

Answer 2

Answer: C.7 inches × 10.5 inches

Step-by-step explanation: Aspect ratio is maintained in an optical magnification.

Aspect ratio is the ratio between the length and the breadth of an image.

A photocopier uses light and lens combination to magnify an image optically in which the aspect ratio is conserved.

The given image has the dimensions 2 inch by 3 inch, so its aspect ratio is 2:3.

Now from the given options we check for the same ratio and arrive at 7:10.5 .

As,

`(7)/(10.5) = (7* 10)/(10.5* 10) = (70)/(105) = (14)/(21) = (2)/(3)`
