Step-by-step explanation:
The correct answer is C. Keep flame above or below eye level. This is because keeping the flame of a candle above or below eye level is not an etiquette rule for using candles as a centerpiece. The other options are etiquette rules to follow when using candles as a centerpiece.
A. Use only if planning to light: This is an etiquette rule because candles should only be used if you plan to light them.
B. Use after 4 p.m.: This is an etiquette rule to consider because candles are typically used in the evening or nighttime, and using them after 4 p.m. ensures they create the desired ambiance.
D. Use only in fall or winter: This is also an etiquette rule because candles are often associated with cozy and warm atmospheres, which are commonly associated with the fall and winter seasons.
