Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.387\% 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 additional words.
Options:
a: COc1cc(-c2noc(C)c2/C=C/c2ccc(N)cc2)cc(OC)c1OC
b: Cc1cccc(NC(=O)CCc2c(C)nn(-c3ccc(N4CCOCC4)nn3)c2C)c1
c: Cc1ccc(C(=O)NCC(=O)OCC(=O)N(CC(C)C)c2c(N)n(Cc3ccccc3)c(=O)[nH]c2=O)cc1
d: O=C1Cc2ccccc2C(=O)N1c1ccccc1
Answer: d. O=C1Cc2ccccc2C(=O)N1c1ccccc1
