Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 2.615% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] C=CCNc1nc(C2(C)CC3(CC(C)(C)OC3=O)C(=O)O2)cs1
[b] C1=C(c2ccccc2)CCNC1.Cl
[c] O=C(Cn1c(=O)oc2ccccc21)Nc1ccc(Cl)cc1
[d] O=C(Nc1cccc(S(=O)(=O)N2CCCCC2)c1)c1cc2ccccc2o1
Answer: b. C1=C(c2ccccc2)CCNC1.Cl
