Explanation opens after your attempt
B. (c=2)
Concept
From (-4(c+1)+2c=0), we get (-2c-4=0). Therefore (c=-2) is required.
Why this answer is correct
The correct answer is B. (c=2). From (-4(c+1)+2c=0), we get (-2c-4=0). Therefore (c=-2) is required.
Exam Tip
(-4(c+1)+2c=0) से (-2c-4=0) मिलता है। इसलिए (c=-2) होना चाहिए।
