Task: Answer the multiple choice question.
Query: Which drug has a 4.353\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:

(b) CC(=O)c1c(C)[nH]c(C(=O)COc2ccc3ccc(=O)oc3c2)c1C
(c) COc1ccc(OC)c(/C=N/N=C(\N)c2nonc2N)c1
(d) CCC/C(O)=C1\C(=O)CC(C)(C)CC1=NCc1ccccc1
Answer: b. CC(=O)c1c(C)[nH]c(C(=O)COc2ccc3ccc(=O)oc3c2)c1C
