An aldehyde is an organic compound containing a terminal carbonyl group (C = O). This functional group, consisting of a carbon atom bound to a hydrogen atom and an oxygen atom via double bond (the general formula: CHO) is called the aldehyde group. In a reaction of the addition of alcohol to the carbonyl group, it forms hemiacetals. 
On the picture attached it is shown the reaction of alcohol addition to the carbonyl group with the major organic product <span>formed in the reaction.</span>

I can tell you there certainly is enough information, so we can eliminate the fourth option right away.
Group two elements tend to form 2+ cations, and nitrogen forms 3- anions. To make a stable substance, we need those to cancel out. Calling the group 2 element X:
N2X3 would cause the charge to be 2(-3) + 3(2) = 0
This would mean 3 ions of X and 2 anions of N would be a stable ionic compound.

Explanation:
En 1945, durante la Segunda Guerra Mundial, dos ciudades japonesas; Hiroshima y Nagasaki fueron bombardeadas con bombas atómicas durante el ataque ofensivo.
Hiroshima fue bombardeada el 6 de agosto de 1945 mientras que Nagasaki fue bombardeada el 9 de agosto de 1945.
Las bombas provocaron la muerte instantánea de aproximadamente 120.000 personas y obligaron al emperador japonés a rendirse incondicionalmente.
