show me hoe to solve these types of questions

You are asked to implement a delay of 0.2ms in KL25 with a clock rate of 10MHz. The delay will be implemented using a loop of 9 instructions. Each of the first eight (8) instructions take 1 clock cycle and the last conditional branch instruction takes 2 clock cycles when the branch takes place and one clock cycle otherwise. The most accurate number of iterations for the loop run is? (a) 200 times (b) 250 times (c) 1,000 times (d) 2,000 times
