Task: Answer the multiple-choice question.
Query: Which drug has a 4.109\% 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. COc1ccc(C2CC(c3ccccc3)=NN2C(=O)CN2CCN(Cc3ccccc3)CC2)cc1
b. COc1ccccc1N(C(=O)NCc1ccccc1)C1=NCC(C)S1
c. CCN1C(=O)C(c2ccc(O)cc2)(c2ccc(O)cc2)c2ccccc21
d. CNc1ccc(Cl)nn1
e. CCCn1c(N)c(C(=O)CSc2nnc(N)s2)c(=O)[nH]c1=O
Answer: d. CNc1ccc(Cl)nn1
