Task: Answer the MCQ question.
Question: Which drug exhibits a 22.026\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(CSc1nc2sc3c(c2c(=O)n1-c1ccccc1)CCCC3)N/N=C/c1ccccc1C(=O)O
b O=C(NC1CCCCC1)c1cc([N+](=O)[O-])[nH]n1
c COc1cccc(C(c2c(C)[nH]n(-c3ccccc3)c2=O)c2c(C)[nH]n(-c3ccccc3)c2=O)c1O
d COc1ccc(CN(C(=O)COc2ccccc2)c2ccccc2C(=O)O)cc1
Answer: d. COc1ccc(CN(C(=O)COc2ccccc2)c2ccccc2C(=O)O)cc1
