Final answer:
The term for treating someone unfavorably due to their face is D) Physiognomy, which differs from discrimination such as racism or ageism.
Step-by-step explanation:
Treating someone unfavorably due to their face is known by the term D) Physiognomy. Physiognomy is not a form of discrimination, but rather an outdated belief that a person's character or personality traits can be deduced from their facial features. Discrimination, however, refers to the unjust or unequal treatment of individuals based on specific characteristics such as race, age, or gender identity. An example of discrimination based on age would be ageism, the term coined by Dr. Robert Butler in 1968 to describe actions that are prejudiced against older adults. Racism is another form of discrimination that involves prejudice and negative actions toward an individual based solely on their racial group membership. All forms of discrimination, including racism and ageism, are societal issues that can have significant negative impacts on the targeted individuals and groups.
