At which point does the SMC curve cut the SAC curve? Give reason in support of your answer.

Solution
SMC (i.e. MC) curve custs SAC (i.e. AC) curve from below at minimum point of AC curve show in Fig. As long as SAC is falling, SMC is less than SAC and when SAC is rising, SMC is greater than SAC. So SMC curve cuts SAC curve from below at its minimum point.
