Task: Answer the multiple-choice question.
Question: Which drug exhibits a 10.432\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1cc(C(=O)O)nc2ccccc12
b: Cc1ccccc1C(O)(Cc1ccccc1)C1CN2CCC1CC2.Cl
c: CCOc1ccccc1OCCC(=O)OCC(=O)c1ccc[nH]1
d: CCOC(=O)/C(C)=N/NC(=O)c1cccc([N+](=O)[O-])c1
e: C=CCNC(=O)c1ccc(OC)cc1OC
Answer: a. COc1cc(C(=O)O)nc2ccccc12
