Task: Answer the multiple-choice question.
Query: Which drug exhibits a -0.939\% 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) COc1ccccc1/C=C/CN1CCCC(CO)(Cc2cccc(Cl)c2)C1
(b) O=C(Nc1nc(-c2ccccc2)cs1)C1CCCO1
(c) CCCCc1ccc(NC(=S)NCC2CCCO2)cc1
(d) CCC(=O)Oc1ccc2c(C)cc(=O)oc2c1C
Answer: b. O=C(Nc1nc(-c2ccccc2)cs1)C1CCCO1
