Question

which is an impact to the environment from vessel sending?
increased particulate matter is inert in the environment.
increased particulate matter in the marine environment builds up eroding beaches.
increased particulate matter entering the water may block sunlight needed for the growth of aquatic grasses.
increased particulate matter in the estuarine environment creates more substrate on which oysters grow.

Explanation:

Vessel sonar can stir up sediment, increasing particulate matter in water. This can block sunlight needed for the growth of aquatic plants like aquatic grasses. The other options are not typical direct impacts related to vessel sonaring. Increased particulate matter in the environment in general (first option) is too vague. Building up eroding beaches (second option) is not a main sonar - related impact. Creating more substrate for oysters (fourth option) is not a common impact of sonar.

Answer:

Increased particulate matter entering the water may block sunlight needed for the growth of aquatic grasses.
