[B]. nitrogen contents
[C]. calcium contents

No answer description available for this question.

I thing its Nitrogen because rainwater dose contain small amount of nitrus and nitric acids as N2 is the most abundant gas in atmosphere thus when lighting sticks it causes nitrogen to react with oxygen to form NO2 N2O5 etc. Which then mix with water vapor to form acids.

Mohd Saleem said: (Feb 7, 2012)  
It must be nitrogen not calcium.

Sangeeta Sherawat said: (Jul 26, 2013)  
It's nitrogen contents because calcium can't be present in rainwater. It is present in soil not in rainwater.

Huma Gul said: (Aug 13, 2013)  
Rain water does not contain calcium in it. Its probably Nitrogen.

Jp.Anand said: (Dec 10, 2013)  
In rainwater large amount of nitrogen present so it must be nitrogen nor calcium.

Joykrishna Mandal said: (Jan 27, 2014)  
According to me, right answer is option B nitrogen contents.

Tehmina said: (May 5, 2014)  
Rain water also contain some mineral of magnesium and calcium so it increases calcium a little.

Huma said: (May 11, 2014)  
We never study in previous classes about rain water contains calcium, mostly it contains acids so that is called acid rain.

Joaquim Joe said: (Aug 1, 2015)  
The correct answer is nitrogen.

Sanjeev said: (Sep 29, 2015)  
Nitrogen is the right answer because lightning stick.

Nwaogu David Chisy I said: (Jul 19, 2016)  
I think the given option is the right answer.

Vipin Kumar said: (Aug 15, 2016)  
Calcium is right. Ocean water is rich in calcium as salts ions.

Sneha Mandal said: (Aug 17, 2016)  
Yes, the answer is obviously nitrogen.

Biswanath said: (Dec 26, 2016)  
The right answer is nitrogen.

Vivek said: (Feb 22, 2017)  
Nitrogen is the correct answer.

Manoj Kumar Sharma said: (Mar 23, 2017)  
I accept that the ocean water is rich in calcium but it does not evaporated by sun light (because of this we obtain salt) so the correct answer is nitrogen.

Keerthana M Lal said: (Jan 20, 2018)  
I don't understand why the answer is Ca? Please explain it.

Sonika said: (Nov 2, 2018)  
As per my knowledge, it is nitrogen contents.

Revathi Agri said: (Mar 16, 2019)  
Nitrogen content is the correct answer.

Vanshika said: (Jun 1, 2019)  
Calcium is the correct answer as rain water is hard water and contains calcium and magnesium. Nitrogen is not correct although it is abundant in nature because it is not much soluble in water even plants need symbiotic bacteria for nitrogen intake.

We can easily see white layer on leaves after raining because of calcium contents in rain water and it's not nitrogen.

Narendra Narkhede said: (Apr 25, 2020)  
Nitrogen, because no any part containging Calcium in the rain water.
