Problem statement: Answer the multiple-choice question.
Question: Which drug has a 4.520\% 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(Nc1csc(Cl)c1)c1ccccc1
[b] Cn1c(-c2nonc2N)nc2ccccc21
[c] N#Cc1c(NC(=O)C2CC2)sc2c1CCCCC2
[d] CC(=O)N1c2ccc(S(=O)(=O)N3c4ccccc4CC3C)cc2CC1C
Answer: a. O=C(Nc1csc(Cl)c1)c1ccccc1
