Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.964\% 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 other words.
Options:
a COc1ccccc1NC(=S)N(CCCN(C)C)Cc1cc2cc3c(cc2[nH]c1=O)OCO3
b Cc1ccc(-c2csc3nnc(SCC(=O)NCc4ccc5c(c4)OCO5)n23)cc1
c Cc1ccc(S(=O)(=O)N2CCN(C(=O)NCc3ccc(F)cc3)CC2)c(C)c1
d N#Cc1ccc(S(=O)(=O)N2CCC(C(=O)Nc3cccc(C(=O)NC4CC4)c3)CC2)cc1
e CNC(=O)Cn1nc(-c2ccc(C)cc2)c2ccccc2c1=O
Answer: e. CNC(=O)Cn1nc(-c2ccc(C)cc2)c2ccccc2c1=O
