Task: Answer the multiple-choice question.
Question: Which drug exhibits a -13.655% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a COc1ccccc1CNCC(O)(c1ccc(Cl)cc1)c1ccc(Cl)cc1
b CC1CCCCC1NC(=O)CCn1ccc2cc(S(=O)(=O)N3CCCC3)ccc21
c COC(=O)/C=C/c1ccc(-n2cncn2)cc1
d Cc1ccnc(SCC(=O)Nc2sccc2C#N)n1
e O=C(COc1ccccc1[N+](=O)[O-])N/N=C/c1ccncc1
Answer: a. COc1ccccc1CNCC(O)(c1ccc(Cl)cc1)c1ccc(Cl)cc1
