Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.036\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(NC1CCCCC1)c1ccc(COCC(F)(F)F)o1
b. CC(O)[C@H]1CC[C@H]2[C@@H]3CC[C@H]4C[C@@H](O)CC[C@]4(C)[C@H]3C(=O)C[C@]12C
c. Nc1c(-c2ccc3c(c2)OCCO3)oc2ccccc2c1=O
d. Cc1cc(Br)ccc1SCC(=O)OCC(=O)NCc1ccc2c(c1)OCO2
Answer: a. O=C(NC1CCCCC1)c1ccc(COCC(F)(F)F)o1
