Task: Answer the multiple choice question.
Query: Which compound has a -41.872% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a S=c1sc2ccccc2n1CCc1ccncc1
b C=C(C)CNC(=S)N/N=C1\CCCCc2ccccc21
c CCN(CC)C(=O)CSc1nc2sc3c(c2c(=O)n1CCOC)CCC3
d O=C(N/N=C/C(Cl)=C\c1ccccc1)c1cccs1
Answer: a. S=c1sc2ccccc2n1CCc1ccncc1
