Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.345\% 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 additional words.
Options:
a CCn1c(SCC(=O)N2CCC(C)CC2)nnc1-c1ccco1
b COc1cccc(NC(=S)N2CCN(C(c3ccccc3)c3ccccc3)CC2)c1
c Cc1c(O)ccc(/C=N/Nc2nc(-c3cccnc3)nc3ccccc23)c1O
d CSc1c(C#N)c(N)nc2sc(C(=O)c3ccc(Cl)c(Cl)c3)c(N)c12
Answer: d. CSc1c(C#N)c(N)nc2sc(C(=O)c3ccc(Cl)c(Cl)c3)c(N)c12
