The correct answer is: B. took a risk.
The new C.M. promised 10kgs. free wheat a month for all rural families. This is a bold promise, and it is not clear how the C.M. plans to fulfill
it. It is possible that the C.M. is taking a risk by making this promise, as it could lead to financial problems for the government if it is not able to deliver on its promise. However, it is also possible that the C.M. is confident that he can fulfill his promise, and that this promise will be popular with rural voters.The other options are incorrect. Option A is incorrect because the C.M. did not take an oath. Option C is incorrect because the C.M. did not extend help to rural families. Option D is incorrect because the C.M. did not cause embarrassment.
