Task: Answer the multiple-choice question.
Question: Which drug exhibits a -4.493\% 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 other words.
Options:
a.) COc1ccc(Oc2ncnc3sccc23)cc1
b.) CCOC(=O)CC1=C(C(=O)OCC)C2(C(=O)N1)C(C(=O)OC)=C(N)Oc1ccccc12
c.) CCOc1ccc(CCNC(=O)CN2C(=O)c3cccnc3Oc3ccc(Cl)cc32)cc1
d.) O=C(CNC(=O)c1cccc(F)c1)OCC(=O)N1CCCc2ccccc21
e.) O=C(NCCCN1CCOCC1)c1ccc(Br)cc1
Answer: b. CCOC(=O)CC1=C(C(=O)OCC)C2(C(=O)N1)C(C(=O)OC)=C(N)Oc1ccccc12
