Mathematics Question from JEE Main 2026 · 23 January, Shift 1

Let a⃗=−i^+j^+2k^\vec{a} = -\hat{i} + \hat{j} + 2\hat{k}, b⃗=i^−j^−3k^\vec{b} = \hat{i} - \hat{j} - 3\hat{k}, c⃗=a⃗×b⃗\vec{c} = \vec{a} \times \vec{b} and d⃗=c⃗×a⃗\vec{d} = \vec{c} \times \vec{a}. Then (a⃗−b⃗)⋅d⃗(\vec{a} - \vec{b}) \cdot \vec{d} is equal to:

  • A

    −4-4

  • B

    44

  • C

    −2-2
