Interesting question; I would probably choose #d.# Why?

Explanation:

The #"mole"# is strictly a NUMBER, like a #"dozen"#, a #"score"#, a #"gross"#. And BY DEFINITION, #"ONE MOLE"#, #6.022xx10^23# #""^12C*"atoms"# have a mass of #12*g#. On the other hand, the units of length are derived units, not strictly numbers, and you are not even using Kosher units...

How many dozen #""^1H# atoms are in one mole of this material? What is the associated mass?

PS I am going to show this to my A2 class tomorrow, and see how many of them know what a mile, yard, foot, furlong, is...
