Consider the following two statements: 

Statement p: The value of sin 120° can be derived by taking θ =   240° in the equation 2sin(θ/2) = (1 + sinθ) - (1 - sinθ).

Statement q: The angles A, B, C and D of any quadrilateral ABCD satisfy the equation cos(1/2(A + C)) + cos(1/2(B + D)) = 0.

Then the truth values of p and q are, respectively, 

(A) F, T 

(B) T, F 

(C) T, T
