T/F scholars do not know why Harappan civilization ended

It is true that scholars do not know why Harappan civilization ended.

Answer: Option A

Explanation:

Scholars do not learn to understand their language. Scholars have mixed opinions about the end of this civilization. While some historians claim that the civilization ended due to natural calamity like earthquake or floods, there is no solid claim of the same.

Sir Mortimer Wheeler claims that the decline is due to foreign invasion as he claimed that the skeletons recovered during excavations had damage which could have been caused due to sharp objects or weapons.
