Solution

The correct option is C $a b - b c, b c - c a, c a - a b$
$a b - b c + b c - c a + c a - a b = 0$
$a - b + a b + b - c + b c + c - a + a c = a b + b c + a c$
$2 p^{2} q^{2} - 3 p q + 4 + 5 + 7 p q - 3 p^{2} q^{2} = - p^{2} q^{2} + 4 p q + 9$
$(l^{2} + m^{2} + n^{2}) + 2 l m + 2 m n + 2 n l$
