Problem statement: Answer the multiple choice question.
Question: Which drug has a 16.294\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. OC(CN1CCN(Cc2ccccc2)CC1)Cn1c2ccccc2c2ccccc21
b. COC(=O)C(C)Sc1n[nH]c(=S)s1
c. CC(=O)/C=C\c1ccccc1OC(=O)c1cc2ccccc2oc1=O
d. COc1ccc(C=O)cc1Cn1cnc2c(cnn2C)c1=O
Answer: c. CC(=O)/C=C\c1ccccc1OC(=O)c1cc2ccccc2oc1=O
