Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.223\% 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 other words.
Options:
a. O=C(CCN1CCCCC1c1cccnc1)NCc1ccccc1
b. CCOC(=O)c1cc(C#N)c(SCC(N)=O)[nH]c1=O
c. COc1ccccc1-c1noc(CSc2nc(C)cc(=O)[nH]2)n1
d. CC(C)Cn1c(/C=C/c2ccccc2)nc2ccccc21
Answer: d. CC(C)Cn1c(/C=C/c2ccccc2)nc2ccccc21
