Task: Answer the multiple choice question.
Question: Which drug has a 3.276\% 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 O=C(NCCc1ccccc1)C(=O)NCC1OCCN1S(=O)(=O)c1ccc(Br)cc1
b COC(=O)/C(C#N)=C/c1ccc(C)o1
c Cc1ccc(-n2ncc3c(=O)[nH]c(SCC(=O)N4CCOCC4)nc32)cc1
d CCCCCCc1cc2cc(C(=O)OCC)c(=O)oc2cc1O
Answer: b. COC(=O)/C(C#N)=C/c1ccc(C)o1
