Task: Answer the multiple-choice question.
Question: Which drug exhibits a 16.189\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1ccc(S(=O)(=O)NCC(=O)N(CC(=O)NCc2ccco2)Cc2ccccc2)cc1
b: COc1ccc(-n2c(=O)[nH]cc(C(=O)Nc3ccc4c(c3)OCCO4)c2=O)cc1
c: Cc1nc2c3ccccc3nc(NNC(=O)CCC(=O)NC(C)C)n2n1
d: CCC(C)[C@H]1CN=C(N)N1CC1CCCCC1
e: Cc1cc(C)cc(NC(=O)NNC(=O)c2cc3occc3[nH]2)c1
Answer: d. CCC(C)[C@H]1CN=C(N)N1CC1CCCCC1
