Task: Answer the multiple choice question.
Question: Which drug has a 18.778\% 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.) CCc1ccc(-c2csc(-c3c[nH]c4ccccc34)n2)cc1
b.) O=C1/C(=C2/NCCN2C2CC(=O)N(c3ccccc3)C2=O)CC/C1=C\c1ccccc1
c.) O=C(CNC(=O)c1ccc2c(c1)OCCO2)N=Nc1c(O)[nH]c2ccccc12
d.) C(=C/c1ccc(/C=C/c2ccccc2)nn1)\c1ccccc1
e.) Cc1ccc(-c2ccc(C(=O)NCCCNC(=O)c3cnccn3)o2)cc1Cl
Answer: e. Cc1ccc(-c2ccc(C(=O)NCCCNC(=O)c3cnccn3)o2)cc1Cl
