Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 4.591\% 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 CCN(CC)S(=O)(=O)c1ccc(S(=O)(=O)NCC2CCCO2)cc1
b COc1cccc(-c2onc3ccc(C(C)=O)cc23)c1
c C=CCNC(=O)CSc1nnc(C(CC)N(C)C)n1C1CCCCC1
d Cn1c(N)nc2ccccc2c1=O
Answer: d. Cn1c(N)nc2ccccc2c1=O
