Answer :

Final answer:

The original question regarding safeguarding classified information does not match the reference content provided, which pertains to chemistry and physics. An estimated answer based on common security practices includes multiple techniques, but an exact number can't be given without specific context. option b is correct answer.

Explanation:

The question seems to be about the basic techniques used to safeguard classified information, however, the reference example questions provided do not match this topic. Instead, they relate to chemistry and physics. In lieu of the provided examples which are unrelated, I'll provide an informed guess based on typical security protocols.

When safeguarding classified information, organizations typically employ multiple techniques. These can include, but are not limited to, the following:

Controlling access to information through clearance levels and need-to-know principles

Securing physical areas where classified information is stored or discussed

Implementing cybersecurity measures to protect digital information

Educating personnel on security protocols and the importance of information security

So, while the question asks how many basic techniques are used, without specific context it's difficult to provide an exact number. Different organizations may implement a varying number of techniques based on their needs and the sensitivity of the information.
