If the tangent to the curve y = x + sin(y) at a point (a, b) is parallel to the line joining the points (0, 32) and (12, 2), then which of the following relations is correct?

The commutator of matrices A and B is defined as [A, B] = AB - BA, and the anti-commutator as {A, B} = AB + BA. If {A, B} = 0, then [A, BC] can be expressed as:
