Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 2.093\% human ether-à-go-go related gene (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: O=C(COc1ccc(Cl)cc1Cl)NC(=O)N1CCOCC1
b: CCOc1cc(CNc2ccc(S(N)(=O)=O)cc2)ccc1OCC(=O)NC(C)(C)C
c: Br.O/C(=C\Sc1nnc(Cc2ccccc2)o1)c1ccc(Br)cc1
Answer: a. O=C(COc1ccc(Cl)cc1Cl)NC(=O)N1CCOCC1
