Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.242% 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 additional words.
Options:
[a] N#Cc1cc2c(nc1SCc1ccccc1)CCCC2=O
[b] O=C(Nc1cccc(Cl)c1Cl)C1CC(=O)N(c2ccc(Br)cc2)C1
[c] Cc1ccc(NS(=O)(=O)c2c(C)[nH]c(C)c2C(=O)N2CCCCC2)c(C)c1
[d] CCCn1c(Sc2nnnn2-c2ccccc2)n[nH]c1=O
Answer: a. N#Cc1cc2c(nc1SCc1ccccc1)CCCC2=O
