Task: Answer the multiple-choice question.
Query: Which drug exhibits a 20.758\% 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. O=C(C1CCCO1)N1CCC(O)(c2ccccc2)CC1
b. CCc1ccc(C(=O)C(C)OC(=O)c2cccc(S(=O)(=O)N3CCOCC3)c2)cc1
c. CCOC(=O)N1CCN(c2cc(=O)n(-c3ccccc3C)c(=O)[nH]2)CC1
Answer: a. O=C(C1CCCO1)N1CCC(O)(c2ccccc2)CC1
