Yes, there is a rule in the NEC that explains this.
NEC 358.30(B)(2) states that "Where rubber-covered conductors are used in a conduit, the minimum radius of the curve of the inner edge of any field bend shall not be less than eight times the internal diameter of the conduit."The answer is C. 8 times. Flag for review
