The answer is C) #1.8xx10^24"C atoms"#

Explanation:

One mole of #"C"_6"H"_12"O"_6"# has a molar mass of #"180.16 g/mol"#. https://en.m.wikipedia.org/wiki/Glucose

One mole of #"C"_6"H"_12"O"_6"# also has 6 moles of carbon atoms.

#90cancel("g C"_6"H"_12"O"_6)xx(1cancel("mol C"_6"H"_12"O"_6))/(180.16cancel("g C"_6"H"_12"O"_6))xx(6cancel("mol C atoms"))/(1cancel("mol C"_6"H"_12"O"_6))xx(6.022xx10^23 "C atoms")/(1cancel("mol C atoms"))=1.8xx10^24"C atoms"#
