Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.454% 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 other words.
Options:
(a) Cc1ccc2nc(-c3cccc(Br)c3)cc(C(=O)NCC3CCCO3)c2c1
(b) CC1CC(C)CN(C(=O)CN2C(=O)NC3(CCCCCCC3)C2=O)C1
(c) CCCn1c(N)c(Sc2ccccc2[N+](=O)[O-])c(=O)n(CCC)c1=O
(d) O=C(O)Cn1c(CC(=O)N2CCCC2)nc2ccccc21
Answer: d. O=C(O)Cn1c(CC(=O)N2CCCC2)nc2ccccc21
