Task: Answer the multiple-choice question.
Query: Which drug has a 2.508\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(CN1CCOCC1)Nc1ccc(C2CCCCC2)cc1
b.) COC(=O)Cc1c(OC)ccn(CCc2c[nH]c3ccccc23)c1=O
c.) O=C(NNC(=S)Nc1ccc(Br)cc1)c1ccccc1Br
Answer: c. O=C(NNC(=S)Nc1ccc(Br)cc1)c1ccccc1Br
