B. It gives an example of a plant that loves the sun.
C. It explains the process of photosynthesis.
D. It introduces an exception to the rule mentioned previously.✓ Correct

Detailed Answer Explanation

This question tests your understanding of how the text is organized. The first sentence sets a rule (need sunlight). The second says 'However' and introduces fungi that don't need it (exception). Authors structure their writing purposefully to guide readers through their ideas. Identify the organizational pattern (cause-effect, compare-contrast, problem-solution) and how each part contributes to the whole. Authors choose organizational patterns deliberately to enhance their message. Recognizing whether a text uses chronological order, cause-effect, compare-contrast, or problem-solution helps you understand the author's purpose and follow the logic.

Key Evidence:

• "However"

• "grow in complete darkness"

Why others are wrong: B (Fungi are not plants, and they don't use sun here.), A (It doesn't say sunlight is bad.), C (Photosynthesis is not explained.).
