Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -0.003\% 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 additional words.
Options:
a C/C(=N/NC(=O)CNC(=O)c1ccncc1)c1ccco1
b O=C(CCC(NC(=O)OCc1ccccc1)C(=O)O)OCc1ccccc1
c CC(C)Cn1c(N)c(C(=O)COC(=O)Cc2cccc(C(F)(F)F)c2)c(=O)n(C)c1=O
d CCOC(=O)C1(CCOc2ccccc2)CCN(Cc2cccn2-c2ncccn2)CC1
Answer: a. C/C(=N/NC(=O)CNC(=O)c1ccncc1)c1ccco1
