A poor question, even by the standards of most multiple choice questions....

Explanation:

NONE of the options give kosher units. We know that #6.022xx10^23# #""^1H*"atoms"# have a mass of #1*g#...and #6.022xx10^23# #""^12C*"atoms"# have a mass of #12*g# and so...

#(16*g*mol^-1)/(6.022xx10^23*mol^-1)=2.66xx10^-23*g#..but this answer has units....#3# does not specify any such.
