Task: Answer the MCQ question.
Query: Which compound has a 7.238\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) CCOc1cc(C(=O)N/N=C/C(Br)=C/c2ccccc2)cc(OCC)c1OCC
b.) CCOc1ccc(NC(=O)CN(C)C(=O)c2ccc(C3SCCS3)cc2)cc1OCC
c.) COc1ccccc1CNCC(O)(c1ccc(Cl)cc1)c1ccc(Cl)cc1
d.) CC(C)OC(=O)CN1C(=O)C(=O)c2ccccc21
e.) COC(=O)Cc1cnc(NC(=O)CSc2nc(C(C)C)cc(=O)[nH]2)s1
Answer: a. CCOc1cc(C(=O)N/N=C/C(Br)=C/c2ccccc2)cc(OCC)c1OCC
