Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.438\% 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 or b without using any other words.
Options:
(a) Cc1nn(-c2ccccc2)c(C)c1/C=N\N1CCN(c2ccc(Cl)cc2)CC1
(b) O=C(N1CCC(n2nc(-c3ccccc3)oc2=O)CC1)C1(c2ccccc2)CC1
Answer: b. O=C(N1CCC(n2nc(-c3ccccc3)oc2=O)CC1)C1(c2ccccc2)CC1
