Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.421\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a Cc1ccnc(NC(=O)c2ccc([N+](=O)[O-])o2)c1
b Cc1[nH]nc2c1C(c1ccc(F)cc1)C(C#N)=C(N)O2
c CCN1CN(Cc2ccccc2)CNC1=S
d O=C(NCC(c1cccs1)N1CCc2ccccc21)c1ccccc1
e C(=NCCCN1CCOCC1)c1ccc2c(c1)OCO2
Answer: a. Cc1ccnc(NC(=O)c2ccc([N+](=O)[O-])o2)c1
