Which prefix means below?

Explanation:
The concept here is how prefixes convey location. Infra- means below or beneath, coming from Latin infra. You can see it in words like infrared, which sits below visible red light in the spectrum, and infrastructure, referring to the underlying framework beneath the surface. That sense of underneath is exactly what this prefix communicates, so it’s the best fit for “below.” Ad- means toward or near (as in moving toward something, like adduction). Intra- means within or inside (as in intracellular). Ac- is a less common directional form and isn’t used to indicate below. So infra- clearly matches the meaning of below.
