Correct answer: b. thick layer of blubber.

Explanation: streamlined bodies (a), flippers/flattened tails (c), and smooth, nearly furless skin (d) all reduce drag or provide propulsion, helping animals move through water. A thick layer of blubber mainly provides insulation, energy storage, and buoyancy — it doesn't aid propulsion and can even increase bulk and drag.
