In triangle

A B C

A: B: C=1: 2: 4

, then

\left(a^2-b^2\right)\left(b^2-c^2\right)\left(c^2-a^2\right)=\lambda a^2 b^2 c^2

, where

\lambda=

(where notations have their usual meaning)

View answer and explanation

Correct option: A

Option A (1) is correct because by substituting the angles and using trigonometric identities, the expression simplifies to 1.
