Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.916\% 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(=O)NNC(=O)c2ccc(S(=O)(=O)N3CCCCC3)cc2)cc1
b: N#CCCN(Cc1cccs1)C(=O)Nc1ccc(F)cc1
c: CCN(CC)CCN(Cc1cc2cc(C)ccc2[nH]c1=O)C(=S)Nc1ccccc1
d: Cc1c(NC(=S)N/N=C/c2ccc(O)cc2)c(=O)n(-c2ccccc2)n1C
Answer: b. N#CCCN(Cc1cccs1)C(=O)Nc1ccc(F)cc1
