Solution

The correct option is A Asexual

In Helianthus or sunflower, the outer or peripheral, zygomorphic flowers are called ray florets; whereas inner or central, actinomorphic flowers are known as disc florets. The ray florets are sterile or asexual as they do not possess any reproductive parts (stamens or pistil) whereas disc florets are complete flowers (they have sepals, petals and at least 1 stamen and 1 pistil). So, the correct answer is 'Asexual'.
