A alternativa correta é a letra "e) I, II, III e IV estão corretas". A toxoplasmose é causada por um protozoário do gênero Toxoplasma, que pode infectar humanos e outros animais. O gato e outros felinos são os hospedeiros definitivos ou completos do Toxoplasma gondii, enquanto humanos e outros animais podem ser hospedeiros intermediários ou incompletos. A toxoplasmose pode ser transmitida por meio da ingestão de oocistos presentes em jardins, alimentos ou objetos contaminados; ingestão de cistos presentes em carnes mal cozidas, especialmente porco e cordeiro; e transmissão congênita ou placentária.
