Task: Answer the multiple choice question.
Query: Which drug has a -4.911\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COc1ccc(N(Cc2cc(=O)[nH]c3ccccc23)C(=O)C(C)C)cc1
(b) CC(Oc1ccc(Br)cc1)C(=O)O/N=C(\N)c1ccncc1
(c) COc1ccc(/C=C/C(=O)OCC(=O)N2CCCCCC2)c(OC)c1
(d) Cc1[nH]c2ccccc2c1C(=O)C(=O)NC1CC(=O)N(c2ccc(F)cc2)C1
Answer: b. CC(Oc1ccc(Br)cc1)C(=O)O/N=C(\N)c1ccncc1
