Task: Answer the multiple choice question.
Query: Which compound has a 9.375\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] O=C(O)c1cccc(NS(=O)(=O)c2ccc3c4c(cccc24)C(=O)N3)c1
[b] O=C(NCCCn1ccnc1)C(=O)NCC1OCCCN1S(=O)(=O)c1ccc(Cl)cc1
[c] COc1cc(Cl)c(C)cc1NC(=O)COC(=O)c1ccc(CN2CCCC2=O)cc1
[d] COc1cccc(CNC(=O)c2cccnc2Sc2ccccc2)c1
[e] O=c1c(-c2ccccc2)c(-c2ccccc2)oc2cc(O)cc(O)c12
Answer: e. O=c1c(-c2ccccc2)c(-c2ccccc2)oc2cc(O)cc(O)c12
