Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.521\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] COc1cc(SC)ccc1C(=O)N1CCN(c2ccc(O)cc2)CC1
[b] COc1ccc(C2=NC(C)(C)Cc3cc(OC)c(OC)cc32)cc1
[c] C/C=C/c1ccc(OCCCNC(C)CC)c(OC)c1.O=C(O)C(=O)O
[d] C=CCN(CC=C)C(=O)Nc1ccc(OCC)cc1
[e] COc1ccc(NC(=O)CSc2c3c(nc4ccccc24)CCCC3)c(OC)c1
Answer: b. COc1ccc(C2=NC(C)(C)Cc3cc(OC)c(OC)cc32)cc1
