C. unless one are
D. not rigid

Answer

C

Explanation

According to the "Subject-Verb Agreement rule", a singular subject takes a singular verb and a plural subject takes a plural verb. However, we use .one. as a singular subject and *ones. as a plural subject so, in the given question, one will take .is as a singular verb. Furthermore, .Unless. cannot be used with a negative word like no, not, never, etc. in a sentence because it becomes a case of superfluousness (not necessary). Hence, .unless one is rigid. will be answer.
