Consider the following Python function.

def PerformTask(S):
    L = [];
    for i in range(0, len(S)):
        if S[i] == "(":
            L.append(S[i])
        elif S[i] == ")" and len(L)>0:
            L.pop()
        else:
            return False
    return True

Which of the following input parameter will result in a return value of “True" in the above?
