Answer

Brief Explanations:

In a textbook, bold words are often important terms that need to be defined. The words "matter," "photosphere," "fusion," and "Kelvin" are likely key concepts in the text. Option B is incorrect because not all bold words are defined in the glossary (they could be defined in - text). Option A is incorrect as there's no indication they are from foreign languages. Option C is incorrect as there's no basis for saying hard - to - understand words are always bold. Option D is incorrect as there's no mention of "bonus words."

Answer:
