Explanation:

To solve this, we analyze each option:

• "acidic" refers to pH, not a physical state. Eliminate.
• "semisolid": Microbial media like agar with less agar is semisolid (e.g., for motility tests). Valid physical state.
• "complex" refers to chemical composition (undefined ingredients), not physical state. Eliminate.
• "solid": Media like agar plates (solidified with agar) are solid. Valid physical state.
• "liquid": Broth media is liquid. Valid physical state.

Answer:

B. semisolid, D. solid, E. liquid
