Task: Answer the multiple choice question.
Question: Which drug has a 1.910\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CC1(C)NC(=O)N(CC(O)CN(c2ccccc2)S(=O)(=O)c2ccc([N+](=O)[O-])cc2)C1=O
b. CCc1ccccc1NC(=O)c1ccccc1N1C(=O)C2C3C=CC(C3)C2C1=O
c. CCOC(=O)N1CCN(C(=O)c2ccc(N(Cc3ccc(C)cc3)S(C)(=O)=O)cc2)CC1
d. COC(=O)CSc1nc(NC(C)=O)nc(C)c1Br
Answer: d. COC(=O)CSc1nc(NC(C)=O)nc(C)c1Br
