Task: Answer the multiple choice question.
Question: Which drug has a -6.326% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CCCN(CC(=O)Nc1ccccc1Br)CC(=O)Nc1ccc(F)c(F)c1F
(b) O=C(Nc1ccncc1)Nc1ccc(Cl)cc1
(c) O=C1N/C(=N/N=C/c2ccc(O)cc2)SC1Cc1ccccc1
(d) Cc1ccnc(N2CCC(C(=O)NCc3ccccc3F)CC2)n1
Answer: b. O=C(Nc1ccncc1)Nc1ccc(Cl)cc1
