Solution

The correct option is A

-91K


Step 1: Given information

We know the relation between the Kelvin scale and the Celsius scale.

We denote the Kelvin scale by K and Celsius scale by C.

We know the relationship between them K=C+273.15

We are given that ratio CK=4

Step 2: Calculate K

So, K-273.15K=4

Or, K-273.15=4K

Or, 3K=-273.15

Or, K=-91.05

So the correct answer is (A) -91K
