Task: Answer the MCQ question.
Query: Which drug has a 14.013\% 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) CCOc1ccccc1C1C(C#N)=C(N)SC(N)=C1C#N
(b) COc1ccc2cc(-c3ccn[nH]3)ccc2c1
(c) CC(C)c1nnc(NC(=O)CCC(=O)N2CCN(C3c4ccccc4-c4ccccc43)CC2)s1
Answer: a. CCOc1ccccc1C1C(C#N)=C(N)SC(N)=C1C#N
