Solution A has 10 times more hydrogen ions than solution B.. The correct option is B.
<h3>What is a pH?</h3>
pH is the potential of hydrogen ions, or measure of hydrogen ion concentration.
It is generally used to determine the acidity and basicity of the solution based on pH scale.
The pH scale is logarithmic, which means that each pH unit contains ten times the number of hydrogen ions as the unit above it. So solution A has 10 times more hydrogen ions than solution B.
Thus, the correct option is B.

Correct matches of terms and its descriptions:
1. Cloning (most controversial method of genetic engineering)
2. hybridization ( breeding organisms because of beneficial traits)
3. recombinant ( DNA DNA from different biological sources that have been combined and culture)
4. selective breeding ( breeding two different species to make a new individual)
Selective breeding is also called artificial selection. Hybridization.is mating organisms of different species to create a hybrid. Cloning produces similar copy of genetically identical individuals.
The correct answer is <span>b. a mother holding a baby.
Babies could be fragile. Thus, it will require an effort when one is holding a baby in their arms. This is because they should be strong and firm at the same time they should be soft and comfortable for the baby. Also, a mother's touch is different. So the best work done in arms is </span><span>b. a mother holding a baby. I hope that this answer helped you. </span>
