Which prefix denotes 'Beyond; excess'?

• A. Extra-
• B. Intra-
• C. Mal-
• D. Ultra-

Answer: (D)

The concept tested is understanding prefixes that convey degree and boundary: which one means going beyond or exceeding the usual limit. Ultra- exactly fits that idea, originating from Latin ultrā meaning beyond. It signals something extreme or surpassing what’s typical, as in ultraviolet (beyond violet) or ultramodern (beyond modern). The other options don’t carry that sense as strongly: intra- means within, mal- means bad, and extra- means outside or additional but not inherently indicating extreme surpassing. So ultra- is the best fit for “Beyond; excess.”
