Task: Answer the multiple choice question.
Question: Which drug has a -5.399\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a CCC(C)[C@H]1CN=C(N)N1CCc1cccc(F)c1
b CC1(C)Cc2[nH]c(=O)c(C#N)cc2CS1
c CCC(CC)CN1C(N(C)C)=NC[C@@H]1CC(C)C
d COc1ccccc1Oc1c(C)oc2c(CN3CCOCC3)c(O)ccc2c1=O
e COc1cccc(CN2CCCCC2c2cccnc2)c1
Answer: b. CC1(C)Cc2[nH]c(=O)c(C#N)cc2CS1
