Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.547\% 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(NCc1ccco1)Oc1ccccc1
b) O=C(NCCCn1ccnc1)NC(C(F)(F)F)C(F)(F)F
c) COc1ccc(CNC(=O)CN(c2ccc(C(C)C)cc2)S(=O)(=O)c2c(C)noc2C)cc1
d) CN(CCc1ccccn1)C(=S)Nc1ccc(Cl)cc1Cl
Answer: a. O=C(NCc1ccco1)Oc1ccccc1
