which feature may form as a result of erosion related to runoff?\ndeltas\ngullies\nflood plains\nstalactites

Brief Explanations:

Runoff - related erosion can carve out narrow channels called gullies in the soil. Deltas form from sediment deposition at the mouth of a river. Flood - plains are areas adjacent to rivers formed by repeated flooding and sediment deposition. Stalactites are formed by the deposition of minerals in caves, not by runoff - related erosion.

Answer:

B. gullies
