Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 5.958\% 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 additional words.
Options:
a. COc1ccc(C(=O)OCCN2C(=O)c3ccccc3C2=O)cc1
b. O=C1C2C(c3ccccc3)C=CC(c3ccccc3)C2C(=O)N1CCO
c. Br.CCCCN1C2=NCCCN2c2ccccc21
d. COc1ccc(CS(=O)c2nc(C)cc(C)c2S(C)(=O)=O)cc1
Answer: b. O=C1C2C(c3ccccc3)C=CC(c3ccccc3)C2C(=O)N1CCO
