Answer 1

The correct option is A Acid

• Cavities, also called tooth decay or caries, are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sipping sugary drinks, levels of acid in food and not cleaning your teeth well.
• Cavities and tooth decay are among the world's most common health problems.
• Sugar isn't the only culprit when it comes to tooth decay. High levels of acid in everyday foods and drinks can be just as harmful. From oranges to wine, high-acid foods and drinks can wear away your teeth, causing decay, sensitivity and discolouring. Hence, Acid causes tooth decay.

So, the correct answer is 'acid'.
