Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.278\% 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.) COc1ccc2nc(SCC(C)=O)c(C#N)cc2c1
b.) CCCC1CCC(C(=O)Nn2c(C)nc3ccccc3c2=O)CC1
c.) CCNC(=O)NC(=O)C(C)On1nnc2ccc(S(=O)(=O)N(CC)CC)cc21
d.) CC(C)(C)C1CCC(OC(=O)CN2CCOCC2)CC1
e.) CC1(C)CC(=O)C2=C(C1)N(CCN1CCOCC1)C1=C(C(=O)CC(C)(C)C1)C2c1ccc(Cl)cc1
Answer: e. CC1(C)CC(=O)C2=C(C1)N(CCN1CCOCC1)C1=C(C(=O)CC(C)(C)C1)C2c1ccc(Cl)cc1
