A.I. Explanation:

Option 1: "Medical insurances are rarely available now."

Explanation: The text does not mention the availability of medical insurances. Instead, it focuses on the rising costs of medical care and stagnant wages. Therefore, this option is not supported by the text.

Option 2: "Medical expenses have increased."

Explanation: The text states that 'medical costs have continued to rise,' which directly supports this option. This increase in medical expenses is a key factor contributing to the financial issues faced by working mothers.

Option 3: "There is an increased number of disease in children and adults today."

Explanation: The text does not mention any increase in diseases. It focuses on the financial strain caused by rising medical costs and stagnant wages, making this option irrelevant.

Option 4: "Salaries of working mothers are not enough as compared to the expenses."

Explanation: The text indicates that 'wages remained stagnant,' which implies that the salaries of working mothers are insufficient to cover rising medical expenses. This directly correlates with their financial struggles.

Option 5: "Other expenses come in the way thereby pushing back the medical expenses."

Explanation: While the text mentions reallocating family funds, it does not support the idea that other expenses are pushing back medical expenses. Instead, it emphasizes the direct impact of rising medical costs on working mothers' finances.
