Task: Answer the multiple choice question.
Query: Which drug has a 2.121\% 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 other words.
Options:
a.) O=C(Nc1ccc2oc(-c3ccccc3F)nc2c1)c1cncc(Br)c1
b.) CCCCc1ccc(-c2csc(/C(C#N)=C\c3ccc(C)o3)n2)cc1
c.) CCN(CC)S(=O)(=O)c1cccc(-c2nn(-c3ccccc3)cc2/C=C(\C#N)C(=O)NCc2ccco2)c1
d.) CN1CCC(OC(=O)c2ccccc2)CC1.Cl
e.) Cc1oc(-c2ccc(Cl)cc2)nc1CS(=O)CC(=O)NCCCN1CCN(Cc2ccccc2)CC1
Answer: a. O=C(Nc1ccc2oc(-c3ccccc3F)nc2c1)c1cncc(Br)c1
