Answer: Last option is correct.

Explanation:

Since we have given that

Length of a blue whale is given by


3* 10^4

Length of an otter is given by


2* 10^3

Number of times the blue whale is longer than the otter is given by


\frac{\text{Length of a blue whale}}{\text{ Length of an otter}}\\\\=(3* 10^4)/(2* 10^3)\\\\=(3* 10000)/(2* 1000)\\\\=(30)/(2)\\\\=15\ millimeters

Hence, Last option is correct.
