D1, 2, 4 only

Correct answer: (B) 2, 3, 4 only

Explanation

Web based studies collect data at the participant's convenience, gather it automatically, and reach people who are physically distant.

The first statement is false, as web studies need far less researcher time per individual.

Data collection at the participant's convenience raises response flexibility.

Automatic data capture reduces manual recording errors.

Distant or scattered participants become reachable online.

Web studies still face concerns over sample representativeness and identity verification.
