Final answer:
Gentamicin can cause severe neurological and kidney damage as it is an aminoglycoside, which is known for these types of side effects.
Step-by-step explanation:
Among the antibiotics listed, Gentamicin is known to cause severe side effects such as neurological damage and kidney damage. This antibiotic belongs to the class of aminoglycosides, which are potent broad-spectrum antibacterials and work by binding to the 30S subunit of bacterial ribosomes. The other antibiotics listed, including Penicillin, Sulfa-TMP (Trimethoprim/sulfamethoxazole), and Tetracycline, have different profiles of side effects. While penicillin can cause severe allergic reactions in some individuals, severe neurological and kidney damage are more characteristic of aminoglycosides like gentamicin.
