Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.903\% 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] O=C(Cc1ccc(Cl)cc1)NCCCNC(=O)c1cccnc1
[b] CCCCC(=O)NC(c1ccc(N(C)C)cc1)c1ccc2cccnc2c1O
[c] CC1CCCCC12NC(=O)N(CC(=O)Nc1ccc(S(=O)(=O)Nc3ncccn3)cc1)C2=O
[d] CSc1cccc(NS(=O)(=O)c2ccc(-c3coc(C)n3)cc2)c1
Answer: a. O=C(Cc1ccc(Cl)cc1)NCCCNC(=O)c1cccnc1
