Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Inadequacy
Inadequacy is a suitable option.
This word is used to describe anything that is not sufficient to accomplish a desired outcome.
It is the opposite of "efficacy," which means capacity to bring about a desired consequence. As a result, "inadequacy" is a suitable antonym.
Compared to other options:
Effect: Although it is not an antonym, this phrase describes the end or effect of an action or occurrence. It is connected to the word "efficacy." Rather, it enhances "efficacy."
Virtue: This word, which is not a good antonym and often relates to moral perfection or goodness, is unrelated to effectiveness.
Potency: This word is similar to "efficacy" and is not an antonym. It describes the ability or capacity to produce an effect.
