Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 3.448\% 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 CC(NC(=O)Cn1nc(-c2ccccc2)c2ccccc2c1=O)c1ccccc1
b COc1ccc(NC(=S)N2CCCC2)cc1OC
c O=C(CNc1ccc(Br)cc1)NNC1=NCCC1
d CC12C(=O)N(c3ccccc3)C(=O)C1C(c1ccccc1)N1CCCN12
e COCCCNCCCCOc1cccc(Br)c1.O=C(O)C(=O)O
Answer: c. O=C(CNc1ccc(Br)cc1)NNC1=NCCC1
