Suppose

a, b, c \in \mathbf{C}

, and

|a|=|b|=|c|=1

and

a b c=a+b+c

, then

b c+c a+a b

is equal to

View answer and explanation

Correct option: C

Option C (1) is correct because using the given conditions |a|=|b|=|c|=1 and abc=a+b+c, we can manipulate the equations to show that bc+ca+ab = 1.
