B Correct answer
Explanation

Late blight of potato is caused by the fungus Phytophthora infestans (though technically an oomycete, historically classified as a fungus). This devastating disease caused the Irish Potato Famine. Viruses, amoebae, and bacteria do not cause late blight - they cause other plant diseases but not this specific condition.
