Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.126\% 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. O=C(CN1CCN(C(=O)c2ccc(-c3nc4ccccc4s3)o2)CC1)Nc1ccc(F)cc1
b. Cc1nc2n(COCCO)cnn2c(=O)c1Br
c. O=C(O)c1c[nH]ccc1=O
d. CCOc1ccccc1OCC(=O)OCc1csc(CC(=O)Nc2ccccc2C)n1
Answer: c. O=C(O)c1c[nH]ccc1=O
