Small amounts of blood are best submitted to a crime

a. after removal from surface of deposition and rehydration.
b. after dried.
c. in a druggists fold.
d. immediately while still wet.

Option B, After Dried

Explanation:

All biological fluids such as blood, semen, saliva etc. are not collected from the crime scene when they are wet or moist. Since, we all aware that all human beings are genetically distinct hence if these fluids are tested after they dry up, no specific impact can occur on the sample and the test result. Also collecting dry sample is much easy and comfortable. The dried samples undergo DNA analysis there by producing a genetic profile which is specific to individuals

Hence, option A is correct

They died due to suffocation.

Explanation:

The whole Lannister’s family died due to the shortage of oxygen in the room because of squirrel’s nest in the chimney. Chimney is the only way for the removal of toxic gases and smoke produced from the burning of wood. The squirrel’s nest block the passage and the smoke and toxic gases stay in the house which causes suffocation and the whole Lannister’s family died.
