Select the most appropriate ANTONYM of the highlighted word.
Science has been trying innumerable methods to prove the existence of the universe, but the biggest pleasure of science is its inability to produce a single theory that explains the whole universe.

Correct option is C

The correct antonym of the highlighted word “pleasure” is “fear.”

Meaning of the given word (with Hindi):

·       Pleasure = a feeling of happiness, delight, or enjoyment; satisfaction derived from an experience. (आनंद/सुख/प्रसन्नता)

·       Example: “Reading good books gives me great pleasure.”

Why “fear” is the best opposite here:

·       Antonyms of pleasure in standard usage include pain, displeasure, misery, suffering, distress. While fear isn’t a perfect dictionary-opposite like pain/displeasure, it represents a negative, aversive emotional state that contrasts directly with the positive, enjoyable state implied by pleasure.

·       Among the given options, only fear clearly denotes a strong negative emotion opposed to enjoyment. Hence, it is the most appropriate antonym available.

Meaning of the correct option (with Hindi) + example:

·       Fear (भय/डर) — an unpleasant emotion caused by the threat of danger, pain, or harm.

·       Example: “He could not enjoy the ride because of his fear of heights.”

Synonyms & Antonyms (for conceptual clarity):

·       Synonyms of pleasure: joy, delight, enjoyment, gratification, bliss.

·       Antonyms of pleasure: pain, displeasure, suffering, distress, misery, fear (contextually opposite in emotional valence).

Why the other options are incorrect (with meanings):

·       A. Inadequacy (अपर्याप्तता/अयोग्यता) — lack of sufficiency or capability. This is about quantity/ability, not an emotional state opposite to pleasure.

·       B. Joy (आनंद/हर्ष) — synonym of pleasure, not an antonym.

·       D. Blandness (फीका-पन/निष्क्रियता) — lack of flavor, liveliness, or excitement; it suggests dullness, not a direct emotional opposite to pleasure.

Conclusion: Given the choices, C. Fear most appropriately opposes pleasure in emotional valence and is therefore the correct answer.
