Even if Uma is unable to make it, I can't most definitely come.

Options

A. No improvement.
B. won't definite
C. needn't more definite
D. shall most definitely

Answer

D

Explanation

.shall most definitely should be used in place of .can.t most definitely.. The phrase .even if used to express something will happen, would happen or would have happened in any case or condition. This conjunction emphasizes that a specific situation will continue no matter what happens. The first sentence is negative and the presence of .Even provides us with a hint that the latter part will be positive. Hence, option d is the correct answer./
