After reaching a certain age, looking back, one realise the evanescence of all things.
Right Answer is: C
Option B has the grammatically incorrect part. With singular pronoun “one”, singular verb should be used. The sentence indicates a general idea; therefore, it should be written in simple present tense. In simple present tense, we add ‘s’ or ‘es’ with main verb to make it singular. Therefore, it should be “realises” instead of “realise”.
