Answer 1

The correct statement is:

Only -ir stem-changers show a stem change in the preterit.

In the preterit tense, only -ir verbs that are stem-changers in the present tense will change in the third-person forms (él, ella, usted, ellos, ellas, ustedes). The changes are typically e → i and o → u. For example, "pedir" (to ask) becomes "pidió" and "dormir" (to sleep) becomes "durmió."
