Problem statement: Answer the multiple-choice question.
Question: Which drug has a 7.534\% 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, or d without using any other words.
Options:
a. COC(=O)/C(C#N)=C/c1ccc(-c2ccc(S(N)(=O)=O)cc2)o1
b. COC(=O)Cc1[nH]n(-c2nc3ccccc3s2)c(=O)c1C(C)=Nc1ccc(OC)cc1
c. CCN1C(=NCCc2cccnc2)N[C@@H](c2ccccc2)[C@H](C(=O)OC)[C@H]1C
d. COCCCNS(=O)(=O)c1cccc(S(=O)(=O)c2cccc(S(=O)(=O)NCCCOC)c2)c1
Answer: c. CCN1C(=NCCc2cccnc2)N[C@@H](c2ccccc2)[C@H](C(=O)OC)[C@H]1C
