As a disease P : and breaks up marriages Q : accidents and suicides R : alcoholism leads to S : affecting all ages The Proper sequence should be:

The correct answer is: C. SRQP

Alcoholism is a disease that affects all ages. It can lead to accidents and suicides, and it can break up marriages. The proper sequence of the sentence is:

• S Alcoholism is a disease.
• R It affects all ages.
• Q It can lead to accidents and suicides.
• P It can break up marriages.

The other options are incorrect because they do not follow the correct sequence of events. For example, option A (SRPQ) would suggest that alcoholism leads to accidents and suicides, which then leads to the disease affecting all ages. This is not the correct order of events.
