A Student Wanted to Plant an Avocado Seed to Try

Multiple Choice

A student wanted to plant an avocado seed to try to grow an avocado plant, but she could not tell which end of the seed was the bottom and which was the top. She asked her friends what she should do. Which friend's suggestion will have the highest success of growing the avocado plant?

A) One friend said it doesn't matter in which direction the seed is planted as long as there is a strong light on the soil, since the shoots will seek the light and turn the seed right side up.
B) One friend said to put the seed in in any direction, because as the seed is watered, it will be able to detect the direction the water is coming from and point the shoots that way.
C) One friend suggested a compromise: Put the seed sideways, since gravity will ensure that the shoots grow up and the roots grow down.
D) One friend said just to put the seed in one direction or the other, because it will only sprout if it is in the right direction, and there's a fifty-fifty chance that it will be in the right orientation.
