Problem statement: Answer the multiple-choice question.
Question: Which drug has a 1.404\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) O=C(Cc1ccc(Br)cc1)NCCc1ccc(Cl)cc1Cl
b.) O=C(COc1ccc(-c2nnco2)cc1)NCc1ccccc1Cl
c.) O=c1[nH]c(CN2CCN(Cc3ccccc3)CC2)nc2scc(-c3ccccc3)c12
Answer: a. O=C(Cc1ccc(Br)cc1)NCCc1ccc(Cl)cc1Cl
