Answer: B. 6 cm

Explanation:

First we take down the information given to us,

distance from the lens to the image (v) = 24cm

distance from the original object to the lens (u) = 8cm

So using the formula

1/u + 1/v = 1/f

Where f is the focal length

So we just input our information

1/8 + 1/24 = 1/f

Therefore;

3/24 + 1/24 = 1/f

4/24 = 1/f

1/6 = 1/f

f = 6

Our focal length = 6cm

Answer:B.6
