To change plural medical words to the singular form, you need to identify the correct singular form for each word. Here's the breakdown for each option:
A. Criterion, criteria: This is incorrect. The singular form of "criterion" is "criterion," while the plural form is "criteria." "Criteria" is the correct plural form, not the singular form.
B. Bacteria, bacterium: This is correct. The singular form of "bacteria" is "bacterium" (no "s" at the end).
C. Lumen, lumina: This is correct. The singular form of "lumen" is "lumen," while the plural form is "lumina."
D. Ganglion, ganglia: This is correct. The singular form of "ganglion" is "ganglion," while the plural form is "ganglia."
The correct conversion of plural medical words to their singular forms is option B (Bacteria, bacterium), option C (Lumen, lumina), and option D (Ganglion, ganglia).
