Correct Answer

A. (7)

Step 1

Concept

In (kx), the coefficient of (x) is (k), so (k=12). Hence (k-5=7).

Step 2

Why this answer is correct

The correct answer is A. (7). In (kx), the coefficient of (x) is (k), so (k=12). Hence (k-5=7).

Step 3

Exam Tip

(kx) में (x) का गुणांक (k) है, इसलिए (k=12)। अतः (k-5=7)।
