Final answer:
The correct answer is OB. Jugar. Jugar is not an o-ue stem-changing verb.
Step-by-step explanation:
The correct answer is OB. Jugar. Jugar is not an o-ue stem-changing verb. Stem-changing verbs undergo a change in the stem vowel when conjugated, while jugar does not. For example, the verb volver changes from 'o' to 'ue' in the present tense, like 'vuelvo', 'vuelves', 'vuelve', etc. Dormir changes from 'o' to 'ue' as well, like 'duermo', 'duermes', 'duerme', etc. Poder also changes from 'o' to 'ue', like 'puedo', 'puedes', 'puede', etc. However, jugar remains the same throughout its conjugations, such as 'juego', 'juegas', 'juega', etc.
