(a) $(- 1) \times (- 1)$
(b) $(- 1) \times (- 1) \times (- 1)$
(c) $(- 1) \times (- 1) \times (- 1) \times (- 1)$
(d) $(- 1) \times (- 1) \times (- 1) \times (- 1) \times (- 1) \times (- 1)$

Solution

(a) $(- 1) \times (- 1) = 1$
(b) $(- 1) \times (- 1) \times (- 1) = - 1$
(c) $(- 1) \times (- 1) \times (- 1) \times (- 1) = 1$
(d) $(- 1) \times (- 1) \times (- 1) \times (- 1) \times (- 1) \times (- 1) = 1$
Here value of options (a), (c), (d), are same but value of option (b) is different. Hence, option (b) is the odd one.
