The correct answers are "two" and "too"
Step-by-step explanation:
In language, a homophone refers to a word that has the same sound or pronunciation and in some cases a similar spelling than another word, although each word has a different meaning. This can be challenging for some speakers as one word can be confused with other but also homophones are used for humor in the cases of puns or similar. In the case of the word "to" that is a preposition, this is written similarly and has the same pronunciation than the words "two" that represents number 2 and "too" that means also, therefore these words are homophones because all are pronounced as in the same way. While words such as "toe" or "douce" have a completely different pronunciation.
