Best answer
Correct choice is (b) Produce a symbolic solution

Easy explanation: The solve[] function is an inbuilt function to generate the solutions of one or more than one equations. But the result is always produced in symbolic form. So, even if the answer contains the value of square root of 5, solve[] will return the value as sqrt(sym(5)).
