Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.652\% 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) CCn1nc(NS(=O)(=O)c2ccc(C)cc2)c2cc3ccccc3nc21
b) CC(=O)Nc1ccc(Nc2ccc(N3C(=O)CCCC3=O)cc2[N+](=O)[O-])cc1
c) CCCCC(=O)c1c(C)cc(C)[nH]c1=O
d) Cc1ccc(Nc2cc(C)c(O)c(C)c2)cc1
Answer: c. CCCCC(=O)c1c(C)cc(C)[nH]c1=O
