It is NOT necessary to balance the equations of organic reactions. Therefore, you CANNOT predict the product of reaction based on math.
Here below shows the reaction between an amine and HNO₂ in cold acidic solution.
1° amine + HNO₂ → N₂ gas
2° amine + HNO₂ → an insoluble oil of N-Nitrosamine (RR'N-N=O)
3° amine + HNO₂ → ammonium salt
The given amine is a 2° amine as the N atom in the molecule is bonded to 2 alkyl groups.
So, an insoluble oil of N-Nitrosamine (RR'N-N=O) is formed as the product.
Hence, the answer: the first one
The conversion is shown below:

"Chemical Aid" website shows a reaction:
5CH3CH2NH2 + 3HNO3 --> 4N2 + 4H2O + 5CH3CH2OH

1) is correct. A secondary amine reacts with nitrous acid to form an N-nitroso amine.

I see that you were able to re-categorize your question. Well done. High school chemistry was a long time ago, but I'm going to say that the first one is correct, based on the math involved.
