Problem statement: Answer the multiple choice question.
Query: Which drug has a 2.381\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CC12CCCC[C@@H]1CCC1C2CCC2(C)C1CC[C@@]2(O)CNCCO
[b] CCCCOCCCNC(=O)C1CCCCC1
[c] O=C(CSc1nc2ccccc2o1)N1c2ccccc2Sc2ccc(Cl)cc21
Answer: c. O=C(CSc1nc2ccccc2o1)N1c2ccccc2Sc2ccc(Cl)cc21
