Task: Answer the multiple choice question.
Question: Which compound has a 9.732\% 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 other words.
Options:
a) O=C1NCCCc2nonc21
b) CCOCCCNc1nc2c(C)cccn2c(=O)c1/C=C1\SC(=S)N(CC(C)C)C1=O
c) Cc1cc(C)c2c(NC(=O)C3CC3)nn(C)c2n1
d) COc1ccc(C(=O)Nc2nc3ccccc3s2)cc1
Answer: a. O=C1NCCCc2nonc21
