The correct answer is: B. The receptionist told Umesh to please be seated and wait for his turn.
The receptionist is using a polite request to ask Umesh to sit down and wait for his turn. The use of the word “please” indicates that the receptionist is asking Umesh to do something as a favor, rather than demanding that he do it. The use of the word “seated” indicates that the receptionist wants Umesh to sit down in a specific location, such as a chair or a bench. The use of the word “turn” indicates that Umesh is waiting for something to happen, such as being called to the front of the line.
The other options are incorrect because they do not accurately reflect the tone of the receptionist’s request. Option A is incorrect because it uses the word “requested,” which suggests that the receptionist is asking Umesh for permission to sit down. Option C is incorrect because it uses the word “should,” which suggests that the receptionist is giving Umesh a command. Option D is incorrect because it uses the word “own,” which suggests that Umesh is waiting for something that belongs to him.
