Task: Answer the multiple choice question.
Query: Which drug has a -4.387\% 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: Cc1ccc(C(=O)NNC(=O)COc2ccc(Cl)cc2C)o1
b: C[N+](C)(C)CCN(Cc1ccc(Cl)cc1)c1ccccn1.[I-]
c: Cc1sc2ccccc2[n+]1CCC(C)S(=O)(=O)[O-]
d: O=C(O)Cn1c(=O)cnc2ccccc21
e: Cc1nnc2ccc(-c3ccc(NS(=O)(=O)c4ccc(F)cc4F)cc3)nn12
Answer: a. Cc1ccc(C(=O)NNC(=O)COc2ccc(Cl)cc2C)o1
