Task: Answer the multiple-choice question.
Query: Which drug has a 21.025\% 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 CCCCN(C(=O)CSCC(=O)Nc1ccc(OC)cc1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
b Cc1cc(O)c(C(=O)/C=C/c2ccccc2)c(=O)o1
c O=C(CNC(=O)c1ccc(Cl)cc1Cl)NCC(=O)N1CCC2CCCCC2C1
d CC(=O)Nc1nc2nc(C)cnc2c(=O)[nH]1
e CCn1c(=O)c(C(=O)Nc2ncccc2O)c(O)c2ccccc21
Answer: e. CCn1c(=O)c(C(=O)Nc2ncccc2O)c(O)c2ccccc21
