Task: Answer the MCQ question.
Question: Which drug exhibits a 12.485\% 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(CN1C(=O)COc2ccccc21)N1CCc2ccccc21
b. Cl.N=c1ccn2c(n1)O[C@H]1[C@H](O)[C@@H](CO)O[C@H]12
c. CCCCCn1c(=O)[nH]c2cc(C(=O)NCCCN(C)Cc3ccccc3)ccc2c1=O
d. N#Cc1ccccc1NC(=O)C1SC(=Nc2ccccc2)C(C(=O)Nc2ccc(Cl)cc2)=C1N
Answer: a. O=C(CN1C(=O)COc2ccccc21)N1CCc2ccccc21
