Just put in the given values of y and x

y - x = kt - kc

Now take k common

y - x = k(t - c)

You get (A) as your answer.

I would suggest you to go through a basic algebra book before moving on because it is necessary for you to know how to manipulate an equation (and related algebra) to do well in Quant.
