Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.215\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CCNc1nc(SC(C)C(=O)OC)nc(N(C)C)n1
b Cn1nc(C(C)(C)C)cc1C(=O)NNC(=O)c1ccccc1Cl
c CC(C)C[C@@H](CN(N=O)[C@@H](Cc1ccccc1)CN(C)N=O)N(CCc1ccccc1)N=O.[Na+]
Answer: a. CCNc1nc(SC(C)C(=O)OC)nc(N(C)C)n1
