Answer: (C)

Verified step by step guidance

1. Step 1: Understand the modes of disease transmission, which include direct contact, indirect contact, droplet, airborne, vector-borne, and common vehicle transmission.
2. Step 2: Analyze each option to determine if it involves a mode that facilitates the transfer of pathogens from an infected source to a susceptible host.
3. Step 3: Recognize that touching contaminated surfaces and then touching your face is an example of indirect contact transmission, where pathogens on surfaces enter the body through mucous membranes.
4. Step 4: Identify that sharing eating utensils with an infected person is direct contact transmission, as it allows pathogens to transfer directly from one person to another.
5. Step 5: Note that washing hands regularly with soap and water and receiving vaccines reduce the risk of disease transmission by removing pathogens and providing immunity, respectively, so they do not increase risk.
