Task: Answer the multiple choice question.
Question: Which drug has a -2.748\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) COc1ccc([C@@H]2C(C#N)=C(N)S[C@@H](c3ccccc3)[C@@H]2[N+](=O)[O-])cc1
b.) O=C(Nc1ccc2c(c1)OCO2)c1cc(-c2ccccc2Cl)on1
c.) COCCNC(=S)NC1CC2CCCC(C1)N2Cc1cccs1
d.) COc1ccc(-c2csc(NC(=O)c3ccc(S(=O)(=O)N4CCc5ccccc5C4)cc3)n2)c(OC)c1
Answer: a. COc1ccc([C@@H]2C(C#N)=C(N)S[C@@H](c3ccccc3)[C@@H]2[N+](=O)[O-])cc1
