The correct answer is 'A'. DNA can be obtained from a person through a mouth swab and a blood sample.
Explicación
## Step 1The question is asking about the ways in which DNA can be obtained from a person. DNA, or deoxyribonucleic acid, is the genetic material that carries the instructions for the development and functioning of all living organisms. It is found in every cell of the body.## Step 2The options provided are:- mouth swab and blood sample- mouth swab and urine sample- urine sample and blood sample## Step 3DNA can be collected from various body parts, including the mouth and blood. A mouth swab is a common method of collecting DNA, as it is non-invasive and can be done at home. Blood samples are also a common source of DNA, as they contain white blood cells, which carry DNA.## Step 4Urine samples, on the other hand, are not typically used to collect DNA. This is because urine is mostly water and does not contain cells that carry DNA.
