Final answer:
The correct word to complete the sentence is 'anything,' which fits in a negative statement and avoids a double negative, unlike 'nothing' which would be incorrect, and 'everywhere' is not suitable as it refers to a place. Therefore, the correct answer is option B. anything.
Step-by-step explanation:
The correct answer to the sentence "I went shopping yesterday but I couldn’t find ________ that I liked." is option B, anything. In English grammar, when expressing the absence of something in a negative statement, the word ‘anything’ is often used. The construction with ‘nothing’ would result in a double negative ("I couldn’t find nothing"), which is incorrect in standard English. As for option C, ‘everywhere’, it does not fit the context of the sentence as it refers to a place, not a thing.
