¿qué oración tiene la conjugación correcta? a)yo aprendo mucho en clase. b)yo aprendemos mucho en clase.

The answer would be A

Since A is in the yo form which is singular and matches with the -o in aprendo

Option B wouldn’t match with the Yo form since it ends in -emos which would match with the nosotros form and not the Yo form.

Hope this helps! :3
