In Spanish, the same letter can have an accent and it changes the whole tense. For example, perfect tense "a" means it is perfect tense. The letter "á" for an ending after a verb stem means it is in future tense.
- It is not A because multiple languages use accents such as French. It is not C because you have to look at the ending of the word or memorize the word to know if it is masculine for feminine.
