Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.264% 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, or c without using any additional words.
Options:
a) OCCNc1nc(-c2ccccc2)c2cc(Br)ccc2n1
b) COc1ccccc1CN(C)c1ccc(S(=O)(=O)N2CCN(C)CC2)cn1
c) COCCNC(=O)c1nn2cccnc2c1Cl
Answer: a. OCCNc1nc(-c2ccccc2)c2cc(Br)ccc2n1
