Task: Answer the multiple-choice question.
Query: Which drug exhibits a 15.576\% 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, or c without using any other words.
Options:
a.) CC[C@H](C)[C@H](NC(N)=O)C(=O)NCCc1ccc(Cl)cc1Cl
b.) CCOC(=O)N/N=C/c1cn(Cc2ccc(Cl)cc2)c2ccccc12
c.) COc1cc(C(c2c(C)[nH][nH]c2=O)c2c(C)[nH][nH]c2=O)cc(Br)c1OC
Answer: a. CC[C@H](C)[C@H](NC(N)=O)C(=O)NCCc1ccc(Cl)cc1Cl
