The correct answer is option 2: 1 and 4.

Option 1 states that antibiotics target the synthesis of the cell wall, bacterial protein synthesis, and synthesis of the nuclear membrane. However, this is not entirely accurate. Antibiotics primarily target the bacterial cell wall, which is crucial for the survival and integrity of bacteria. By inhibiting the synthesis of the cell wall, antibiotics can effectively kill bacteria or prevent their growth.

Option 2 correctly identifies the synthesis of the cell wall as a target of antibiotics. Additionally, it mentions the inhibition of mitochondrial function. Mitochondria are organelles found in eukaryotic cells, not bacterial cells. Antibiotics do not typically target mitochondrial function, as they are focused on combating bacterial infections.

Option 3 suggests that antibiotics target bacterial protein synthesis and the synthesis of the nuclear membrane. However, bacterial protein synthesis is a more accurate target of antibiotics, while the synthesis of the nuclear membrane is not commonly affected by antibiotics.

Option 4 correctly identifies the synthesis of the cell wall and bacterial protein synthesis as targets of antibiotics. It does not include mitochondrial function as a target, which is accurate.

Overall, option 2 is the most accurate answer. Antibiotics primarily target the synthesis of the bacterial cell wall and can also
