Task: Answer the multiple-choice question.
Question: Which compound has a 0.512\% 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(NCCCN1CCCC1=O)c1cc(-c2cccnc2)nc2ccc(Cl)cc12
b.) CCOc1cc(N2CCOCC2)c(OCC)cc1NC(=O)COc1cccc(CC)c1
c.) CCN(CC)S(=O)(=O)c1nnc(NC(=O)c2ccco2)s1
Answer: a. O=C(NCCCN1CCCC1=O)c1cc(-c2cccnc2)nc2ccc(Cl)cc12
