A Correct answer
Explanation

Epicalyx is an additional whorl of bracteoles (small bracts) located just below the calyx, typically found in families like Malvaceae (e.g., hibiscus). Bracts are at the base of the inflorescence, tepals are undifferentiated perianth segments, and sepals form the calyx.
