Problem statement: Answer the multiple choice question.
Query: Which drug has a 3.952\% human ether-à-go-go related gene (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 additional words.
Options:
[a] CCOc1cccc(OCCCCN2CCOCC2)c1
[b] Cc1ccc(-c2c(C#N)c(N)nc3c2CCCCC3)o1
[c] Cn1[nH]c(=O)c2ccccc2c1=O
[d] O=C(NNC(=O)C1CCN(S(=O)(=O)c2cccc(C(F)(F)F)c2)CC1)C1CC1
Answer: c. Cn1[nH]c(=O)c2ccccc2c1=O
