Select the most appropriate synonym of the given word:

LUMINOUS

1. A. Dull
2. B. Dim
3. C. Opaque
4. D. Radiant (Correct answer)

Correct Answer

Option D — Radiant

Detailed Solution & Explanation

The correct answer is Radiant.

Key Points

• 'Luminous' means giving off light — bright, shining, intense.
• Its synonym here is Radiant.
• The distractors run the opposite way: 'dull' lacks brightness, 'dim' is faintly lit, and 'opaque' means light can't pass through at all.
• When the target word is about *brightness*, eliminate every option describing a lack of light and the positive-light word remains.
