Task: Answer the multiple choice question.
Query: Which drug has a 6.436\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) O=c1c2ccsc2ncn1Cc1cccc(C(F)(F)F)c1
b) COc1cc([N+](=O)[O-])ccc1-c1ccc(C(=O)Nc2ccc(NC(C)=O)cc2)o1
c) CN(c1ccc(C(=O)N2CCCCC2)cc1)S(C)(=O)=O
d) CS(=O)(=O)c1ccc2nc(NC(=O)CCC(=O)c3cccs3)sc2c1
e) CC1(C)Cc2c(sc3nc(-c4ccccc4Cl)n(N)c(=O)c23)CO1
Answer: a. O=c1c2ccsc2ncn1Cc1cccc(C(F)(F)F)c1
