The pair that accurately represents antonyms is "Big - Small." Antonyms are words that have opposite meanings, and "big" refers to something of considerable size, while "small" pertains to something of little size. Together, they embody the contrast between large and small dimensions, making them a clear example of opposing terms.

The other options do not fit the criteria for antonyms. "Happy" and "Joyful" are synonyms, as both convey a state of positive emotion. "Sad" and "Unhappy" also express similar feelings and can be used interchangeably. Likewise, "Bright" and "Radiant" describe light or vividness and are also synonyms, signifying a similar quality rather than contrasting meanings.
