Task: Answer the MCQ question.
Query: Which drug exhibits a -0.662\% 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, or c without using any additional words.
Options:
a Cn1c(O)c(/C=C2\C=Nc3ccccc32)sc1=Nc1ccc(C(=O)O)cc1
b O=S(=O)(c1cccs1)N1CCN(Cc2ccccc2)CC1
c C/C=C/c1ccc(OCCCCN(C)Cc2ccccc2)c(OC)c1.O=C(O)C(=O)O
Answer: b. O=S(=O)(c1cccs1)N1CCN(Cc2ccccc2)CC1
