Petrol has higher calorific value 44000kj/kg but solid fuels has lesser C.V than petrol. Either gas fuels has also less C.V than petrol.

Liquid Fuels have higher calorific value compared to solid fuels per unit mass because solid fuels contain moisture and unwanted materials that's why they produce ash after combustion.

According to me, it is option B.

Janak said: (Jul 21, 2016)  
Liquid fuel has higher calorific value compared to solid fuel cause solid contained some air, moisture and dust.

Aath said: (Jul 23, 2016)  
Liquid fuels should have high calorific value in general.

Venkat said: (Aug 7, 2016)  
It is Liquid fuel has high calorific value than solid fuel.

Sakthi Balan said: (Aug 23, 2016)  
The calorific value is higher for liquid fuels.

Gurprit said: (Nov 6, 2016)  
Option B is the correct answer.

Dipam said: (Nov 20, 2016)  
Options B is correct, i.e. Liquid fuel have higher calorific value than solid fuel.

Sandip said: (Apr 10, 2017)  
Liquid fuel has higher calorificvalue.

For gases c.v. is 11- 20, solids c.v. is 35- 37 and for liquids c.v. is 43-47 for most of the fuels.

Thanks @Abhishek.

Ranjeet Yadav said: (Jul 30, 2018)  
I think Option A is also correct.

Sarathi said: (Aug 1, 2018)  
I think Option A is correct.

Waqar said: (Aug 1, 2018)  
Liquid has higher calorific value than solid is the correct answer.

Swathi said: (Aug 26, 2018)  
Liquids have lower bond energy and thus have higher calorific value.

Sassman said: (Sep 21, 2018)  
Yes, the answer is B.

Waqar said: (Oct 2, 2018)  
The correct answer is C. I agree.
