Answer: Option (d) is the correct answer.
Explanation:
An atom or element which has the ability to readily gain an electron will have high electronegativity.
Both Beryllium and Calcium are alkaline earth metals and hence they are electropositive in nature.
Whereas both iodine and nitrogen are electronegative in nature. But across the period there is an increase in electronegativity and down the group there is a decrease in electronegativity.
Nitrogen belongs to period 2 and iodine belongs to the bottom of group 17. Thus, we can conclude that nitrogen is more electronegative than iodine.
A). The number of solute particles increases

I used it for one of my chemistry courses before as well.
Hope this helps!
Question A, B, D belongs to scope of physics such as in question A sound under the water travels in form of current and thus these currents are quite lower in deep water where the aquatic animal find stability in comparison to shallow water or near to the water surface where the current is higher.
In question B, speed of sound under the water can be caliberated by the concentration of the ions present in the water and thus higher the concentration greater will the speed of sound.
In C, the current of ocean is higher in summer due to the higher temperature and thus Question A, B, D belongs to scope of physics only C belongs to chemistry asking about the mixing of wastewater in river to increase acidity all relates to pH of water.
