Choose vs. Chose
“Choose” is the base/present form of the verb, while “chose” is its simple past. The past participle is “chosen,” so tense—not spelling preference—determines which form belongs in a sentence.
Use “choose” for the base or present form and “chose” for the simple past: “I choose now,” but “I chose yesterday.”
