Task: Answer the multiple choice question.
Question: Which drug has a 7.177% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCCC(CCC(=O)Nc1cc([N+](=O)[O-])ccc1O)C(=O)O
(b) O=C(CO/N=C/c1c(Cl)cccc1Cl)NNC(=O)c1cccc(Cl)c1
(c) Cc1cc(OCCOCCN(C)CCO)cc(C)c1Cl
(d) O=C(Nc1nc(-c2ccc(Br)cc2)cs1)c1cccnc1
Answer: b. O=C(CO/N=C/c1c(Cl)cccc1Cl)NNC(=O)c1cccc(Cl)c1
