If 'A' means '+', 'B' means '-', 'C' means '×' and 'D' means '÷', then find the value of (1 D 1 C 1) A (2 C 2 D 2) A (3 D 3 C 3) B (4 C 4 D 4).

Correct option is B

(1 D 1 C 1) A (2 C 2 D 2) A (3 D 3 C 3) B (4 C 4 D 4)
=(1 ÷ 1 × 1) + (2 × 2 ÷ 2) + (3 ÷ 3 × 3) - (4 × 4 ÷ 4)
=(1 × 1) + (2 ×1) + (1 × 3) - (4 × 1)
=(1) + (2) + (3) - (4)
= 6-4
