1. I'd say that during the stage of postmortem decomposition known as D. black putrefaction do the body tissues break down and begin to liquefy.
2. The type of crime scene sketch which is best used for evidence located on the floor, walls and ceilings is D. perspective sketch. 

Answer 1): The correct option is black putrefaction

Explanation:

There five stages in which body decomposition occurs:

  • Initial decay:  The bacteria in body starts breaking down the  body tissues into simpler compounds
  • Putrefaction: Bacteria starts getting multiplied the body and further decomposes the body with release in gases with bad odor.
  • Black putrefaction : Due to decomposition color of the body changes with initial stage of internal body parts to start getting liquefy.
  • Fermentation: Fermentation of all internal organs by bacteria.
  • Dry decay: Body starts drying : skin and bones get dried.

Answer 2): the correct option is (D).
