Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.471\% 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, c, d, or e without using any additional words.

b. CCN1CCN(C(=O)CN2C(=O)c3ccccc3S2(=O)=O)CC1.Cl
c. COc1ccc(C(C)=O)cc1COC(=O)c1cc(=O)c2ccccc2o1
d. Cc1ccccc1C(=O)N1CCC(C(=O)NC2CCCCC2)CC1
e. O=C(O)C(=O)O.O=C(c1ccco1)N1CCN(Cc2ccccc2F)CC1
Answer: b. CCN1CCN(C(=O)CN2C(=O)c3ccccc3S2(=O)=O)CC1.Cl
