Task: Answer the multiple choice question.
Query: Which drug exhibits a 10.585\% 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=C1CCCc2c1nc(-c1ccc([N+](=O)[O-])cc1)n2O
(b) Cc1ccc(NC(=O)C2CCCN2C(=O)c2cccs2)c(C)c1
(c) O=C(NCCCN1CCOCC1)C(=O)N/N=C/c1c(Cl)cccc1Cl
(d) CNC(=O)c1c[nH]n2c(=O)c(Cc3ccccc3F)c(C)nc12
Answer: a. O=C1CCCc2c1nc(-c1ccc([N+](=O)[O-])cc1)n2O
