SPOT THE ERROR: After work, I use my computer to find a quickest way home to avoid the terrible traffic in the city.

Explanation

"A" is incorrect. The correct phrase should be "the quickest way home" instead of "a quickest way home." The definite article "the" is needed to indicate that it is the quickest among all possible ways. There is an error here.The error in the sentence is the use of "a" before "quickest way home." The correct phrase should be "the quickest way home" to properly indicate that it is the quickest among all possible ways. Thus, the correct option to mark the error is B) A.
