Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.603\% 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. CCOC(=O)C1CCCN(Cc2ccccc2Cl)C1
b. CC(=O)NC1C(OCc2ccccc2)OC(CO)C(OC(C)=O)C1OC(C)=O
c. Cc1ccc(CCNC(=O)C23CN(Cc4ccccc4)CC2C(c2cccc([N+](=O)[O-])c2)=NO3)cc1
d. COc1ccc(-n2c(SCC(=O)/C(C#N)=C(\C)N)nc3ccccc3c2=O)cc1OC
Answer: a. CCOC(=O)C1CCCN(Cc2ccccc2Cl)C1
