The correct answer is B. Histoplasma capsulatum.Histoplasma capsulatum is a fungus that can cause histoplasmosis, an infection that primarily affects the lungs. One of the distinguishing features of H. capsulatum is its ability to form a capsule, which is a protective layer surrounding the fungal cell. The capsule helps the fungus evade the host's immune system and contributes to its pathogenicity.The other options listed are also fungi that can cause infections in humans, but they do not have a capsule:A. Cryptococcus neoformans: This fungus can cause cryptococcosis, primarily affecting the lungs and central nervous system. It does not have a capsule.C. Blastomyces dermatitidis: This fungus can cause blastomycosis, affecting the lungs, skin, and other organs. It does not have a capsule.D. Coccidioides immitis: This fungus can cause coccidioidomycosis, affecting the lungs and other organs. It does not have a capsule.Therefore, the correct answer is B. Histoplasma capsulatum.
