If someone believe that it is never ethical to eat meat, then they believe that right and wrong is defined by

b. social context
c. concrete circumstances
d. none of the above

If someone believe that is never ethical to eat meat, they believe that right or wrong is defined by personal belief/prejudice

Ithink is public relations
