Question: There are four sentences A, B, C, D where the underlined word is used either correctly or incorrectly. Choose the option which lists all the sentences where the underlined word is used correctly in a sentence.
A. He did not waver in unbelief about the promise of God but was strengthened in faith, giving glory to God.
B. Harry signed an insurance waver before surgery.
C. All these legends waver between the theory of creation, or rather of manufacture, and the theory of evolution.
D. Will this constitute a waver of such right?
"waver" means to become weak or to falter.
"waiver" means to relinquish a right.
Thus, the correct use of "waver" is done in A and C only and hence, the answer is option C.
Sentences B and D should have "waiver" instead of "waver".
