Correct option is B
Option (b) contains an error.
Explanation: The subject “Nature” is singular, so the verb must also be singular. The correct verb is “has”, not “have”.
Correct sentence: Nature has its own way of teaching us through different life experiences...
Grammatical Rule Used:
Subject-Verb Agreement – A singular subject takes a singular verb; a plural subject takes a plural verb.
Example: The sun has its own light. (NOT “have”)
Even though “nature” refers to a broad entity, it is treated as singular in grammar.
Meanings of other parts (no errors):
(a): Correct – expresses the method
(c): “cure” is correctly plural to agree with plural subject “experiences”
(d): No error – “may seem” correctly applies to plural noun “experiences”
