Correct Answer

C. (-7)

Step 1

Concept

In (kx), the coefficient of (x) is (k), so (k=-11). Hence (k+4=-7).

Step 2

Why this answer is correct

The correct answer is C. (-7). In (kx), the coefficient of (x) is (k), so (k=-11). Hence (k+4=-7).

Step 3

Exam Tip

(kx) में (x) का गुणांक (k) है, इसलिए (k=-11)। अतः (k+4=-7)।
