Task: Answer the multiple choice question.
Query: Which compound exhibits a -9.888% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: Cn1cccc1/C=N/NC(=O)Cn1cnc2ccccc21
b: CCOC(=O)c1ccc(N=c2sc(C(=O)OC)cc(=O)n2CCCN2CCOCC2)cc1
c: C/C(=N\NC(=O)C1(C)CC1(Br)Br)c1ccc(NC(=O)c2ccc(C)o2)cc1
d: CCOC(=O)CSc1nc2c(c(=O)[nH]c(=O)n2C)n1CCCc1ccccc1
e: O=C(NCCCn1ccnc1)/C(=C\c1ccccc1Cl)NC(=O)c1ccccc1
Answer: a. Cn1cccc1/C=N/NC(=O)Cn1cnc2ccccc21
