Problem statement: Answer the multiple choice question.
Question: Which drug has a -5.302\% 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) OCCC1CN(Cc2cnc(N3CCCC3)s2)CCN1Cc1ccccc1
b) C[n+]1ccn(CC(=O)c2ccc(Br)cc2)c1.[Br-]
c) O=C(OCC(=O)N1CCCC1=O)c1cc(Cl)ccc1O
Answer: c. O=C(OCC(=O)N1CCCC1=O)c1cc(Cl)ccc1O
