Clicker Question

Firstly I was not able to attend the past class so any help and suggestions for my questions would be great!

The Question:

What is the proper equation for photosynthesis?

a) CO₂ + H₂O + Energy = C₆H₁₂O₆ + 6O_2
b) C₆H₁₂O₆ + 6O₂+ Energy = 6CO₂ + 6H₂O
_{c) 4}CO₂ + 6H₂O + Energy = C8H₁₀O₆ + 4O_2
d)6CO₂ + 6H₂O + Energy = C₆H₁₂O₆ + 6O<sub>2
e)None of the Above


This was not revised because I was not in class but if there is a more effective way to use this question please let me know. 


Update: After reading the paper by Beatty et al (2006) I had decided to add e) none of the above to trick up the question and ad the oops-go-back design to the question</sub>
