Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.908\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CCOC(=O)c1cnc(SCC(=O)Nc2ccc(N3CCOCC3)cc2)nc1N
b) COc1ccc2oc(=N)c(C(=O)Nc3ccc(F)cc3)cc2c1
c) C=CCN1C=C2C(=O)C(C)(OC(=O)CC)C(=O)C=C2C=C1CCCC
Answer: a. CCOC(=O)c1cnc(SCC(=O)Nc2ccc(N3CCOCC3)cc2)nc1N
