Problem statement: Answer the multiple choice question.
Query: Which drug has a 10.556\% 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 other words.
Options:
a CN(CCC#N)C(=O)COC(=O)c1ccc(Cl)cc1O
b S=C(NCCc1ccccc1)N1CCCCC1
c O=C(O)CCc1ccc(-c2cccs2)n1NC(=O)c1ccccc1Br
d CN(C)S(=O)(=O)c1ccc(NC(=O)CN2CCCCCC2)cc1
Answer: a. CN(CCC#N)C(=O)COC(=O)c1ccc(Cl)cc1O
