The concept of a godzilla-like character is very archetypal. Archetypes are common or typical versions of the person or thing. For C and D, those are very unique and uncommon situations. Although B can happen, it still isn't typical.
It would be A. since archetype means a character that is very typical of that role. I mean, when you say a giant reptile-like creature, you just think of godzilla and destruction, so terrorizing a city would be very typical of a character like that.
