💡 Solution & Explanation

Elementary reactions can only have integer orders (1, 2, or 3) based on their molecularity. Therefore, any reaction with a fractional order must be complex. The rate-determining step of a complex reaction is an elementary step and thus must have an integer order, not a fractional order. Therefore, correct answer is C.
