Options

  1. A(\mathrm{C}_{11} \mathrm{H}_{18} \mathrm{O}_{12})
  2. B(\mathrm{C}_{12} \mathrm{H}_{20} \mathrm{O}_{12})
  3. C(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11})
  4. D(\mathrm{C}_{14} \mathrm{H}_{20} \mathrm{O}_{10})

Correct answer

C. (\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11})
