What is the correct form of the irregular verb ser in the preterite tense for the pronoun yo?
The correct form of the irregular verb ser in the preterite tense for the pronoun yo is "Fui".
Explanation:
Fui is the only option in the preterite tense for the pronoun yo. In Spanish, the verb "ser" (to be) is irregular in the preterite tense and has a unique conjugation for each subject pronoun. When referring to "I" (yo), the correct form is "fui". The other options, "Soy" (I am), "Fuimos" (we were), and "Somos" (we are), do not match with the pronoun yo in the preterite tense. Therefore, the answer to the question is "Fui".
