2-Methyloxetane (one stereocentre: a pair of enantiomers, 2) + 3-methyloxetane (1) + tetrahydrofuran (1) + ethyloxirane (one stereocentre: a pair of enantiomers, 2) + 2,2-dimethyloxirane (1) + cis-2,3-dimethyloxirane (meso, 1) + trans-2,3-dimethyloxirane (a pair of enantiomers, 2) + cyclopropyl methyl ether (1) = 2 + 1 + 1 + 2 + 1 + 1 + 2 + 1 = 11 (plain oxetane is C₃H₆O, so it is not counted).

Ans. 11
