Definitely, the correct answer is option B. When Ca(OH)2 is added into a beaker, the solution will turn into pink when the indicator phenolphthalein is added. This is due to the hydroxide ions from the calcium hydroxide dissolved in water. The compound dissociates into calcium ions and hydroxide ions.
