Explanation:

To determine the characteristic of troche dosage form, we analyze each option:

• The first option ("Troches are coated to prevent them from dissolving in the stomach") is incorrect as troches are for oral mucosa (mouth) dissolution, not stomach - related coating.
• The second option ("Troches are held in the mouth until dissolved") is correct. Troches (lozenges) are designed to be retained in the oral cavity to dissolve, allowing for local or systemic absorption via the mouth's mucosa.
• The third option ("Troches are designed to dissolve quickly on the tongue, usually in 60 seconds or less") describes sublingual tablets (like nitroglycerin sublingual tablets), not troches.
• The fourth option ("Troches are intended to be chewed before swallowing") is incorrect; troches are not meant to be chewed.

Answer:

The second option (Troches are held in the mouth until dissolved)
