Answer:

Option B and C

Explanation:

However, in order to capture the land for dam construction several local people are displaced from their native locations. This is one of the negative effect of construction of hydro-power dam.

Also, in order to produce electricity water is stored at greater heights by withdrawing water from canal or river. This causes reduction in water level.
