Question

question 7
the appearance of alligatoring at a fire scene:
a helps identify chemicals used to start fires.
b is an indicator of mass arson.
c is a sure sign of arson.
d has no investigative significance.

Explanation:

Alligatoring refers to the cracking of a surface (like paint or wood) due to heat. It doesn't directly identify chemicals (A is wrong). It's not an indicator of mass arson (B is wrong). It's not a sure - sign of arson as it can occur in non - arson fires too (C is wrong). It has limited investigative significance on its own as it just shows heat exposure.

Answer:

D. has no investigative significance.
