c is correct answer
C is correct answer
Yes, C is the correct answer.
When hooks are formed in deformed bars, the internal radius of bend should be atleast 3 times the diameter of bar. & The length of the straight bar beyond the end of the curve should be atleast 4 times the diameter of the bar.
C is the correct ans
