Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.225% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. Cn1c(SCC(=O)Nc2ccc(F)cc2)nc2c([nH]c3ccccc32)c1=O
b. N#Cc1c(NC(=O)c2ccncc2)sc2c1CCC2
c. CCC(C)C1NC(=S)N(Cc2ccccc2)C1=O
d. CCOC(=O)c1c(C)[nH]c(C)c1C(=O)COC(=O)/C=C/c1ccco1
Answer: b. N#Cc1c(NC(=O)c2ccncc2)sc2c1CCC2
