Task: Answer the MCQ question.
Query: Which drug exhibits a 5.542\% 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: CCCCCCSC1=C(C#N)C(c2ccccc2)CC(=O)N1
b: CCOC(=O)c1c(/N=C/c2c(O)n(-c3ccccc3F)c(=S)[nH]c2=O)sc2c1CCCC2
c: CCc1[nH]nc2c1C1(CCN(C(=O)OCc3ccccc3)CC1)C(C#N)=C(N)O2
Answer: a. CCCCCCSC1=C(C#N)C(c2ccccc2)CC(=O)N1
