Task: Answer the multiple choice question.
Query: Which drug has a 0.210\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCn1c(C)nnc1SCC(=O)Nc1cccc(Cl)c1
b. O=C(COc1ccc(Cl)cc1Cl)NCCCN1CCOCC1
c. CC(=O)Nc1ccc(NS(=O)(=O)c2ccc(-c3csc(C)n3)s2)cc1
d. COc1cccc(N/C(SCc2ccccc2C)=C(/C#N)C(=O)NCc2cccs2)c1
Answer: a. CCn1c(C)nnc1SCC(=O)Nc1cccc(Cl)c1
