Problem statement: Answer the multiple choice question.
Query: Which drug has a 20.058\% 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) O=C1/C(=C/c2ccc(O)cc2)COc2ccccc21
b) CCCCC(=O)N/N=C/c1c(O)n(-c2ccccc2)c(=O)[nH]c1=O
c) O=C(Cn1cc([N+](=O)[O-])cn1)N1CCN(c2ccccc2)CC1
d) Cc1ccc2nc(C)n(-c3ccc(F)cc3)c(=O)c2c1
e) COCCCn1c(=O)c2sccc2n2c(CCCC(=O)N3CCN(c4ccccn4)CC3)nnc12
Answer: a. O=C1/C(=C/c2ccc(O)cc2)COc2ccccc21
