Task: Answer the MCQ question.
Query: Which drug exhibits a 12.512\% human ether-à-go-go related gene (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) CNC(=S)N/N=C/c1cn(CCOc2ccccc2OC)c2ccccc12
(b) Cn1c(NNC(=O)c2ccc(C(C)(C)C)cc2)cc(=O)n(C)c1=O
(c) O=Cc1c(N2CCCCC2)nc2ccccn2c1=O
(d) CC(C)OCC(O)CCc1n[nH]c(=S)n1-c1ccccc1
Answer: c. O=Cc1c(N2CCCCC2)nc2ccccn2c1=O
