Final answer:
To show the first name, last name, and gender of patients whose gender is 'M', you would need access to a database with patient information.
Step-by-step explanation:
To show the first name, last name, and gender of patients whose gender is 'M', you would need access to a database with patient information. Using SQL, you can write a query to retrieve the required information. The query would be something like:
SELECT firstName, lastName, gender FROM patients WHERE gender = 'M';
This query would return the first name, last name, and gender of all male patients in the database.
