Answer :
The root word of unlocked is lock. The "lock" is the root word, and the addition of the prefix "un-" and the suffix "-ed" modifies the root word to create the word "unlocked." The correct option is B.
Root words are the basic building blocks of words. They are the core or fundamental part of a word to which prefixes and suffixes can be added to form new words or alter the meaning of the root word. Root words carry the main meaning of a word and are usually derived from a specific language or origin. For example: The root word "port" means "to carry." From this root word, we can form words like "portable" (able to be carried), "transport" (to carry across), and "export" (to carry out).
Thus, the ideal selection is option B.
