Task: Answer the MCQ question.
Query: Which drug exhibits a -40.536\% 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, c, d, or e without using any other words.
Options:
(a) COc1ccc(CCNCc2ccc(Br)cc2)cc1OC.O=C(O)C(=O)O
(b) COc1ccc2cc(OCC(=O)NNC(=O)Nc3ccc(OC)c(OC)c3)ccc2c1
(c) O=C1C=C(c2ccc(O)cc2)C[C@@H](c2ccc3c(c2)OCO3)C1
(d) O=C(NC(c1ccccc1)c1ccccc1)C1(c2cccs2)CCOCC1
(e) COc1ccc(/C(C)=N/NC(=O)C2CC2)cc1
Answer: a. COc1ccc(CCNCc2ccc(Br)cc2)cc1OC.O=C(O)C(=O)O
