B

brainliest! These bases completely dissociate in solutions of 0.01 M or less. The other bases make solutions of 1.0 M and are 100% dissociated at that concentration. There are other strong bases than those listed, but they are not often.

Strong bases are bases which completely dissociate in water into the cation and OH- (hydroxide ion). The hydroxides of the Group I (alkali metals) and Group II (alkaline earth) metals usually are considered to be strong bases. These are classic Arrhenius bases. Here is a list of the most common strong bases.

LiOH - lithium hydroxide

NaOH - sodium hydroxide

KOH - potassium hydroxide

RbOH - rubidium hydroxide

CsOH - cesium hydroxide

*Ca(OH)2 - calcium hydroxide

*Sr(OH)2 - strontium hydroxide

*Ba(OH)2 - barium hydroxide

A strong base has been indicated with the ability to be a good conductor of electricity. Hence, option B is correct.

What is the base?

Bases are defined as compounds that have the ability to form the release of the negative ions or the hydroxide ions in the solution. The acids release hydrogen or proton, thereby bases tend to have the ability to neutralize acids.

The pH has been the measure of the solution to be able to accept or donate the protons and electrons. The pH has been measured on a scale of 1-14 with the acids having a pH of less than 7, and the pH of bases tends to move towards 14. 7 is the neutral pH.

The strong bases form the dissociation of the ions in the solution more readily, and ions contribute as the medium, thereby forming the conduction of the electricity. Hence, option B is correct.
