Study the list of sentences.
i. if plants are placed under a green light, then they will stay the same height because they will not grow.
ii. if plants are left in a dark room, then they will increase in height because plants do not need light energy to grow.
iii. if plants require carbon dioxide to grow, then plants exposed to more carbon dioxide will grow more quickly.
which option is true about whether the sentences are correctly formatted hypotheses?
a )sentence ii is not a correctly formatted hypothesis because it is factually inaccurate.
b )sentence i is not a correctly formatted hypothesis because it does not explain why green light might affect plant growth.
c )all of the sentences are correctly formatted hypotheses because they all include “if … then …” statements.
d )sentence iii is not a correctly formatted hypothesis because it does not use the word “because.”
