Task: Answer the MCQ question.
Question: Which drug exhibits a 9.375\% 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 other words.
Options:
a O=C(NCCc1ccccc1)c1ccc2c(c1)N(Cc1ccccc1)CCS2
b Cc1ccc(NC(=O)CSc2nc(=O)n(CCCN3CCOCC3)c3c2CCCC3)cc1
c COc1ccc(NC(=O)c2c(N)no[n+]2[O-])c(OC)c1
d C=CCC1(C#N)C(SC)=NC2=C(C(=O)CC(C)(C)C2)C1c1ccc(Br)cc1
Answer: d. C=CCC1(C#N)C(SC)=NC2=C(C(=O)CC(C)(C)C2)C1c1ccc(Br)cc1
