A alternativa correta é a letra c) I, II e III estão corretas. I- A superfície é bastante lisa, pois não possui vilosidades. II- As criptas de Lieberkühn são mais longas e retas do que no intestino delgado. III- O epitélio é colunar e possui mais células caliciformes do que no intestino delgado. A alternativa d) está incorreta, pois a lamina propria não é composta de tecido conjuntivo reticular rico em células.
