Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 5.010\% 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) COc1cccc(Cn2c(=O)c3[nH]cnc3n(-c3ccccc3C)c2=O)c1
b) O=C(CSc1nnc(-c2ccncc2)o1)N1CCCC1
c) COc1ccc(NC(=O)CN(C)C(=O)c2oc3c(ccc4ccccc43)c2C)cc1
d) COCCN(C(=O)CSc1nnc(-c2cccc(F)c2)n1N)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
Answer: a. COc1cccc(Cn2c(=O)c3[nH]cnc3n(-c3ccccc3C)c2=O)c1
