Problem statement: Answer the multiple-choice question.
Question: Which drug has a 10.974\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) O=C(Cn1nnc(-c2ccc(Cl)cc2)n1)NCc1ccco1
b.) COc1ccc2c(c1)[C@H]1[C@H](CO2)[C@H](c2ccccc2)[C@]2(C)C(=O)Nc3cc(Cl)ccc3C(=O)N12
c.) COc1ccc(-c2ccc3oc(-c4ccc(OC)cc4)c(C#CC4(O)CCCCC4)c3c2)cc1
d.) CCCCN(C)CCNC(=O)Cn1c(=O)sc2ccccc21
Answer: a. O=C(Cn1nnc(-c2ccc(Cl)cc2)n1)NCc1ccco1
