Explanation:

The correct answer is option 'C', which is "Medical Tourist".

Definition:
Medical tourism refers to individuals who travel to another country specifically to seek medical treatment at hospitals that offer world-class facilities at a lower cost than what they would have to pay in their own countries. It involves traveling to another country for medical care, which can include a wide range of treatments such as elective procedures, surgeries, or specialized medical treatments.

Reasons for Medical Tourism:
There are several reasons why individuals choose to be medical tourists:

1. Cost: One of the primary reasons for medical tourism is the cost advantage. Many countries, particularly developing countries, offer medical treatments at significantly lower costs compared to developed countries. This cost advantage attracts individuals who need expensive medical procedures but cannot afford them in their own countries.

2. Quality of Care: Medical tourists often seek treatment in countries that are known for their world-class healthcare facilities and highly skilled medical professionals. These hospitals and clinics provide top-notch medical care and follow international standards, ensuring high-quality treatment.

3. Availability of Treatment: Some medical procedures or specialized treatments may not be available or have long waiting times in an individual's home country. Medical tourism allows them to access these treatments immediately or with minimal waiting periods in countries where they are readily available.

4. Privacy and Confidentiality: Some individuals prefer to seek medical treatment in a foreign country to maintain their privacy and confidentiality. By traveling abroad, they can ensure that their medical condition and treatment remain discreet.

5. Tourism Opportunities: Medical tourism often combines medical treatment with leisure travel. Patients and their companions can explore and enjoy the attractions and activities in the destination country, making it a more holistic and enjoyable experience.

Conclusion:
"Medical Tourist" is the appropriate term for foreigners who travel to another country specifically for medical treatment at hospitals that offer world-class facilities at a lower cost. This term encompasses the primary motivation of seeking medical care abroad and highlights the unique aspect of combining healthcare with tourism.
