Answer:
Option C) is correct
That is t=StartFraction p Over s Subscript 1 Baseline minus s Subscript 2 Baseline EndFraction
It also can be written as 
Step-by-step explanation:
Given equation can be written as below:

Now to solve the equation for t:

Taking common term t outside on RHS we get


Rewritting the above equation as below

Therefore option C) is correct
That is t=StartFraction p Over s Subscript 1 Baseline minus s Subscript 2 Baseline EndFraction
It also can be written as 
Answer:
