Jane told Jill that the name "sunflower" comes from the fact that sunflowers follow the sun in the sky throughout the day. Jane

said
that sunflowers actually turn around on their stems to find the sun. To test this idea, Jane and Jill designed an experiment. They
grew a pot of sunfowers outside in natural sunlight, one pot in the house near, but not directly in front of a window, and the final pot
inside the house, away from all windows. All other growing conditions were the same: soil, water, pot size. The girls could not
regulate the outdoor temperature, but since it was spring, the day and night temperatures were pretty close to the indoor temperature.

A. To water the plants exactly the same time each day.

B. To place a shade over the window at different times throughout the day.

C. To track the direction the outdoor sunflower heads were facing throughout the day.

D. To check the direction the sun flower heads or facing each hour throughout the day.

C. To track the direction the outdoor sunflower heads were facing throughout the day.

Explanation:

The main aim of the experiment being conducted by Jane is to track the direction the outdoor sunflower heads were facing throughout the day.

The whole set up is designed to test the claim that sunflowers do follow the sun in the sky throughout the day.

From experiment, Jill should be able to track the changes in the orientation of flower head throughout the day.
This will rightfully support his claims .
