The first responders are the ones who reaches at the crime scene before anyone else. The first responders are usually the police officers. The duty of the first responders is to provide any aid or assistance to the victims that may be present on the scene. The first responders then secure the crime scene so that the scene is not contaminated.

Hence, the answer is 'Option D - renders aid and assistance'.

The CSI team members arriving on the crime scene after the first responders have left with the victim should immediately secure the crime scene. The securing of the crime scene is necessary so that the evidences present at the scene are not contaminated and can be collected for forensic tests.

Hence, the answer is 'Option A - secure the crime scene'.
