Task: Answer the multiple choice question.
Query: Which drug has a 18.644% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] Cc1cccc(N(CC(=O)NC2CCCC2)C(=O)c2c(C)noc2C)c1
[b] O=C(NC(Cc1c[nH]c2ccccc12)C(=O)O)c1cccs1
[c] CCN(CC)c1ccc(/C=N/NC(=O)c2cccc(S(=O)(=O)N3CCOCC3)c2)cc1
[d] CCOC(=O)c1ccc(NC(=O)CN2C(=O)C(=O)N(CC(C)C)C2=O)cc1
[e] COC(=O)c1cc(CSc2nnc(-c3ccccc3)c(-c3ccccc3)n2)oc1C
Answer: b. O=C(NC(Cc1c[nH]c2ccccc12)C(=O)O)c1cccs1
