Step-by-step explanation:

See attachment for complete question

Analysing each of the options.

Option 1. 1 to 400

First, calculate the difference

Difference = 400 - 1 = 399

Then divide by the initial values

%increase = 399/1

%increase = 399

Convert to percentage

%increase = 399 * 100%

%increase = 39900%

This doesn't represent 400% increase

Option 2: 9 to 45

First, calculate the difference

Difference = 45 - 9 = 36

Then divide by the initial values

%increase = 36/9

%increase = 4

Convert to percentage

%increase = 4 * 100%

%increase = 400%

This represent 400% increase

Hence, option B answers the question.
