Answer: low

Key idea: "Intense" means very strong, extreme in degree, force, or feeling.

• Why "low" is correct: "Low" denotes a small amount or degree and therefore directly contrasts with the high degree implied by "intense."

• Why the other choices are incorrect:

  • "smooth" refers to texture or surface quality, not intensity.

  • "serious" refers to importance or gravity, not degree of strength.

  • "diluted" means made weaker by mixing or lessening concentration; it is related to reduced strength in some contexts but is less directly the general opposite of "intense" than "low."

Therefore, "low" is the best antonym of "intense."
