Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.333\% 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 other words.
Options:
[a] Cl.O=C(COc1ccc(F)cc1)NCCN1CCCC1
[b] Cn1cnc2cc(NCc3cccs3)ccc21
[c] CCc1ccc(N2CC(C(=O)N/N=C/c3ccccc3OC)CC2=O)cc1
[d] CCOC(=O)C1=C(C)N(c2ccc(OC)cc2)C(=O)/C1=C\c1ccc(O)c(OCC)c1
[e] Cc1ccc(S(=O)(=O)n2nc(-n3c(C)ccc3C)c3c(F)cccc32)c2ccccc12
Answer: b. Cn1cnc2cc(NCc3cccs3)ccc21
