21. The following python code is applied for the four arrays d1—d4. d1 = np.array([1, 0, 0, 1, 0, 0]); d2 = np.array([0, 1, 0, 1, 1, 0]); d3 = np.array([0, 0, 0, 0, 0, 0]); d4 = np.array([1, 1, 0, 0, 1, 0]). Consider the following statements. (a) func(d1, d2)[2] = 0 (b) func(d2, d4) = d3 (c) func(d1, d2) = d4 (d) func(func(d1, d4), d2) = d3 Which of the above statements is CORRECT? (A) (a)(b) (B) (a)(c)(d) (C) (b)(c)(d) (D) All of the above are correct (E) None of the above is correct
