Final answer:
c. Attend public gatherings
In Philadelphia during Colonial Times, every man could most likely attend public gatherings, as voting and land ownership were restricted based on property and certain religious qualifications.
Step-by-step explanation:
During Colonial Times in Philadelphia, not every man could vote in elections, own land, or attend public gatherings. Political participation and voting rights were reserved primarily for property owners and tax payers, representing the 'elite' who had a financial stake in the community.
In many colonies, religious tests further restricted voting, and women generally did not have the right to vote. Considering this, the most accurate answer to the question of what every man could do in Philadelphia during Colonial Times is c. Attend public gatherings, as this would be the most likely activity that did not have restrictions based on property ownership or religious affiliation.
