Answer:

Option B

Explanation:

If the larger triangle (Preimage) is dilated by a scale factor 'k' to form the image triangle (small triangle),

Scale factor =
\frac{\text{Length of one side of the image triangle}}{\text{Length of one side of the preimage}}

k =
(3)/(2.4)

Therefore, Option B will be the correct option.
