Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.261\% 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)c1cc(S(=O)(=O)NCc2ccc(Br)cc2)c[nH]1
b) Cc1cc(C(=O)N/N=C/c2cn(C)nc2C)c2ccccc2n1
c) COc1cc2c(cc1OC)CN(C(=O)CSc1nc(N)c(C#N)cc1C#N)CC2
d) COc1ccc(-c2cc3ccccc3n2CC(O)CN2CCOCC2)cc1
Answer: c. COc1cc2c(cc1OC)CN(C(=O)CSc1nc(N)c(C#N)cc1C#N)CC2
