Task: Answer the multiple-choice question.
Query: Which compound has a 2.626% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1ccc(C(=S)N2CCCCCC2)cc1
b: CC(Sc1nc2nn(-c3ccccc3)c(=O)c-2c2n1CCCCC2)C(N)=O
c: C/C(=N\NC(=S)NC1CCCCC1)c1ccc(C)o1
d: CC1=C(C(=O)Nc2ccccc2)C(c2cccs2)n2nnnc2N1
Answer: a. COc1ccc(C(=S)N2CCCCCC2)cc1
