The examination is going to commence on the 10th of this month.

The correct answer is B. The word “commence” means to start or begin. The other options are incorrect because they do not mean to start or begin. Option A, “finish,” means to end. Option C, “cancel,” means to stop or not do something. Option D, “continue,” means to keep going or do something again.

The sentence “The examination is going to commence on the 10th of this month” means that the examination will start on the 10th of this month. The examination is not finished, canceled, or continuing. It is starting.
