Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 7.996\% 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 additional words.
Options:
[a] CC(=C/C(=O)O)/C(=C/c1ccccc1)C(=O)O
[b] O=c1c(-c2ccccc2)coc2c(CN3CCCC3)c(O)ccc12
[c] CC1Cc2ccccc2N1S(=O)(=O)c1cccs1
[d] CCC1CCCCN1CC(=O)c1c(C)[nH]c2ccccc12
[e] COc1ccc(OC)c(C2CC(=O)NC(SC)=C2C#N)c1
Answer: b. O=c1c(-c2ccccc2)coc2c(CN3CCCC3)c(O)ccc12
