Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.819% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1ccccc1C(=O)NC(=O)CSc1nnc(SC)s1
[b] CCN1C(=O)C(NC(C)=O)c2cc(OC)ccc21
[c] O=C(NCc1ccco1)C(=O)NCC1OCCN1S(=O)(=O)c1ccc(Br)cc1
[d] CN(CC(=O)Nc1cccc(F)c1)C(=O)/C=C/c1cn(Cc2ccccc2)nc1-c1cccnc1
Answer: b. CCN1C(=O)C(NC(C)=O)c2cc(OC)ccc21
