1,000-year-old lotus seeds

Some thousand-year-old lotus seeds have been unearthed by villagers in a county in Henan. About one or two dozen lotus seeds were excavated from eight to nine meters underground inside a pit hole left after the construction of an expressway. Experts said the lotus seeds were quite possibly grown in the Song Dynasty and settled down and imbedded into the ground after a change in course of the Yellow River. Among all seeds, the lotus seed has the longest life, from 830 years to 1,250 years, as its hard shell protects it from dryness and moisture.

Which of the statement is CORRECT?

A. The lotus seeds were found 8-9 meters under the Yellow River

B. The lotus seeds were found by expressway builders

C. The area where the county is located could have been part of the Yellow River before
