Task: Answer the multiple-choice question.
Question: Which drug has a 11.732\% 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=C(c1ccc(Br)o1)N(Cc1ccccc1)c1ccccn1
b. CCOC(=O)c1c(NC(=O)Cn2nc([N+](=O)[O-])c(Br)c2C)sc2c1CCC(C)C2
c. COC(=O)c1ccc(CSc2nnc(C)n2N)o1
d. COc1cccc(C2CC(c3cccs3)=NN2C(=O)CCC(=O)O)c1OC
Answer: a. O=C(c1ccc(Br)o1)N(Cc1ccccc1)c1ccccn1
