Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Gap 17: "The ancients _____ the cotton plant the 'Daughter of the Sun'". The context is giving a name/title to something. "Called" is the correct verb for assigning a name. "Realized" and "believed" don't fit grammatically. "Said" would require "said that" or direct quotes. The ancients CALLED it by this name.
