Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.387\% 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, or d without using any additional words.
Options:
a: Cn1c(=O)c(C(=O)NNC(=O)c2ccc(Br)cc2)c(O)c2ccccc21
b: COc1ccc(NC(=O)C/C(C)=N/NC(=O)c2ccncc2)c([N+](=O)[O-])c1
c: O=C1NC(=S)CN1c1ccccc1
d: O=C(NCC1(c2ccccc2)CCCC1)C(=O)N1CCOCC1
Answer: a. Cn1c(=O)c(C(=O)NNC(=O)c2ccc(Br)cc2)c(O)c2ccccc21
