A alternativa correta é a letra d) Escleroblastos. Essas células são responsáveis pela produção das espículas, que são estruturas de sustentação das esponjas. Os pinacócitos são células que revestem a superfície externa da esponja, os porócitos são células que formam poros na parede do corpo da esponja e os espongioblastos são células que produzem as células que formam o tecido interno da esponja.
