Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.890\% 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.) COc1ccc(C(c2c(N)[nH]c(=S)[nH]c2=O)c2c(N)[nH]c(=S)[nH]c2=O)cc1
b.) CSc1ccc(CN(C)C(=O)C(Cc2ccccc2)NC(=O)c2ccccc2)cc1
c.) O=C(COc1cccc2ccccc12)N/N=C/c1ccc(Sc2nc3ccccc3s2)o1
d.) COc1ccc(CNC(=O)Cn2ncn3c(cc4ccccc43)c2=O)cc1
Answer: a. COc1ccc(C(c2c(N)[nH]c(=S)[nH]c2=O)c2c(N)[nH]c(=S)[nH]c2=O)cc1
