Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.008\% 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.) Cn1c(=O)c2c(nc(CN3CCN(Cc4ccccc4)CC3)n2CCN2CCOCC2)n(C)c1=O
b.) CCn1c(=O)cc(N2CCC3(CC2)OCCO3)[nH]c1=O
c.) CCNC(=S)N/N=C/c1ccc(OCC(=O)Nc2ccc(C)cc2)cc1
Answer: a. Cn1c(=O)c2c(nc(CN3CCN(Cc4ccccc4)CC3)n2CCN2CCOCC2)n(C)c1=O
