Task: Answer the multiple choice question.
Query: Which drug exhibits a 14.152\% 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) COc1ccc(-c2csc(Nc3cc(C)ccn3)n2)cc1C
b) O=C(c1ccc2nc(Cc3ccccc3F)oc2c1)N1CC[C@H](O)C1
c) C[C@@H](NC(=O)c1nc[nH]c1C(=O)N1CCc2ccccc2C1)c1ccccc1
d) CCCc1nc(SCc2ccc(Cl)cc2Cl)n[nH]1
Answer: a. COc1ccc(-c2csc(Nc3cc(C)ccn3)n2)cc1C
