Solution

The correct option is D $$12.25\ g$$
Grams of concentrated sulphuric acid needed 
= $$1N\times 49\times 0.250\ liter=12.25\ grams.$$
For example, if we take $$6.9 mL$$ of concentrated sulfuric acid and diluted it to $$250 mL$$, you would have a $$1 N H_{ 2 }{ SO }_{ 4 }$$ solution.
Conclusion: Hence, the option $$(B)$$ is correct.
