「茂る」の読み方は「しげる」です。植物が生い茂ることを表します。

be luxurious · grow thickly · be rampant

Explanation:

The verb “茂る” (しげる) means “to grow thickly” or “to be luxuriant.” In the context of the sentence, “夏の野山は、草や木が茂っていた” means “In the summer, the fields and mountains were lush with grass and trees.” The correct reading of “茂る” in this context is “しげる,” which is conjugated to “しげっていた” in the past progressive tense.

• のびていた: This is the past progressive tense of “伸びる” (のびる), which means “to grow” or “to stretch.”
• ふえていた: This is the past progressive tense of “増える” (ふえる), which means “to increase” or “to grow in number.”
• はえていた: This is the past progressive tense of “生える” (はえる), which means “to grow” (for plants), but it does not convey the sense of growing thickly.
• しげっていた: This is the correct past progressive tense form of “茂る” (しげる), meaning “to grow thickly” or “to be luxuriant.”

Therefore, the correct answer is “しげっていた.”
