Problem statement: Answer the multiple choice question.
Query: Which drug has a 0.884\% 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 Cc1ccc(C(=O)NC2CC(C)(C)NC(C)(C)C2)cc1Cl
b O=C(CSCc1ccc(Cl)cc1)Nc1nccs1
c Cc1cccc(N/C(N)=N/c2nc(C(F)(F)F)cc(=O)[nH]2)c1C
d CNC(=S)NCCN1CCOCC1
Answer: d. CNC(=S)NCCN1CCOCC1
