Percentage of hydrogen will be- B. 11.1%
The property depicted in question is - Law of constant composition, which is also known as law of definite proportion and Proust's law.
The law states that a chemical compound will have constant composition irrespective of its source and method of preparation.
The question states that pure water sample is being taken, and we all know that universally water has constant composition of H2O.
Thus, hydrogen content in any amount of water from anywhere in world will be same.
