Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -11.270\% 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 additional words.
Options:
a O=C1NC2(CCN(Cc3ccccc3)CC2)Oc2ccccc21
b O=C(O)c1cccc(S(=O)(=O)N(Cc2ccccc2)c2ccc(Cl)cc2)c1
c C[C@H](N)c1nnc(SCc2ccc(Cl)cc2Cl)o1.Cl
Answer: c. C[C@H](N)c1nnc(SCc2ccc(Cl)cc2Cl)o1.Cl
