None of the above

Detailed explanation-1: -This equation shows that the more hydrogen ions a solution has, the fewer hydroxide ions it must have. So: an acidic solution that has a large amount of H+ will have very little OH–. And a basic solution that has very little H+ will have more OH–.
Detailed explanation-2: -The definition of an alkali is: “A substance with free hydroxide ions (OH-) in solution”. The pH scale indirectly measures the concentration of H+ ions in solution. Because alkalis have more OH-than H+ ions, their relative concentration of H+ is low and so the pH value will be high.
Detailed explanation-3: -To give you the short answer: An acidic solution has a high concentration of hydrogen ions (H +start superscript, plus, end superscript), greater than that of pure water. A basic solution has a low H +start superscript, plus, end superscript concentration, less than that of pure water.
Detailed explanation-4: -A solution is neutral if it contains equal concentrations of hydronium and hydroxide ions; acidic if it contains a greater concentration of hydronium ions than hydroxide ions; and basic if it contains a lesser concentration of hydronium ions than hydroxide ions.
Detailed explanation-5: -Answer and Explanation: An acid will have a higher concentration of protons (H+) relative to hydroxide ions (OH-). The higher the concentration of protons in the acid, the stronger it will be. A base will have a higher concentration of hydroxide ions (OH-) relative to protons (H+).
