Task: Answer the multiple choice question.
Query: Which compound exhibits a -4.048\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCOc1ccccc1NC1=C(Cl)C(=O)N(Cc2ccccc2)C1=O
b: COc1ccc(S(=O)(=O)N2CCOC2CNC(=O)C(=O)NCCc2ccc(S(N)(=O)=O)cc2)cc1
c: COc1ccc(CCC(=O)N2CCCSC2=Nc2ccc(C(C)=O)cc2)cc1
d: C=CCN(Cc1cccs1)C(=O)CN1CCN(S(=O)(=O)c2ccc3c(c2)OCCCO3)CC1
e: CCNc1nc(NC(C)C)nc(Oc2ccc(=O)n(C)n2)n1
Answer: a. CCOc1ccccc1NC1=C(Cl)C(=O)N(Cc2ccccc2)C1=O
