Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.348\% 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) COc1cccc2[nH]c3c(N4CCC(C)CC4)ncnc3c12
b) Br.Cc1csc(=Nc2ccccc2)n1Cc1ccco1
c) Cc1[nH]c2ccccc2c1C(=O)CNc1nccs1
d) COc1ccc2ccccc2c1C(O)c1nccn1C
Answer: c. Cc1[nH]c2ccccc2c1C(=O)CNc1nccs1
