Answer:
The answer will be 4D
Explanation:
According to the problem the focal length of the lens is given
Now the power can be calculated by the formula given below
Power = 1/focal length (in meter)
Therefore for this question
the focal length is given in cm , we have converted it into meter.
Let the power of the lens will be P
Hence P = 1/ - 0.25 = 4 D(negative)
