The correct answer is:

(d) all of the mentioned

Greases perform better than oils in situations requiring high bearing loads and shock loads, slow journal speeds, and temperature extremes. Their thicker consistency provides superior load-bearing capacity, maintains stability under low speeds, and withstands a wide range of temperatures, making them ideal for demanding conditions.
