The sentence talks about the sun shining and casting something warm on the beach.
Step 1: Understand options
- Light: general term for visible illumination, could fit but is less descriptive.
- Ray: refers to a narrow beam of light; less appropriate for the warm ambiance.
- Glow: a soft and steady light that suggests warmth; best fits the sentence.
- Shine: verb meaning to emit light, not a noun to fill the blank.
Step 2: Choose the best fit
Option (C) "Glow'' is the best choice as it conveys warmth and gentle light.
