Task: Answer the MCQ question.
Question: Which drug exhibits a 1.689\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(N/N=C/C=C/c1ccccc1)c1cc2c(ccc3ccccc32)o1
b.) CN1C(c2ccc(F)cc2)=CS/C1=C(\C#N)c1nnc2n1-c1ccccc1SC2
c.) CCOc1ccccc1CN1CCN(S(C)(=O)=O)CC1.O=C(O)C(=O)O
Answer: a. O=C(N/N=C/C=C/c1ccccc1)c1cc2c(ccc3ccccc32)o1
