Hint: Antacids are the bases that are used to reduce the excess acid in the stomach. During digestion, hydrochloric acid is secreted in the stomach. When the amount of hydrochloric acid is increased in the stomach, then antacids like aluminium hydroxide, magnesium hydroxide, sodium bicarbonate (baking soda) etc. are used. These antacids are used to get relief from heartburn, an upset stomach, and indigestion.
Complete Step by Step Answer:
Although both calcium and magnesium metal accidentally catches fire which cannot be put out by using $C{{O}_{2}}$ based extinguishers. But magnesium is used to prepare an antacid, which is used as a medicine for acidity. This antacid is a suspension of $Mg{{(OH)}_{2}}$in water. The ignition temperature of magnesium is very low. This is the reason why magnesium can burn very readily. Magnesium can produce such an intense bright light that it can temporarily cause blindness. The magnesium fire cannot be extinguished very easily with $C{{O}_{2}}$.
Therefore the correct option is Option: (B)$Mg$.
Note: Antacids can sometimes cause problems like nausea, headaches, constipation, etc. The antacids are of various types, ranging from liquids to chewable tablets to tablets that can be dissolved in water to drink. Although a person does not require a prescription for taking an antacid, a person with some serious health problems may contact their doctor before taking any antacid.
