2. Uninterrupted Power Supply (UPS)
3. Antivirus software
Explanation:
Antivirus software, or Anti-virus software (also known as AV software), otherwise called anti malware, is a PC program used to forestall, distinguish, and eliminate malware.
Antivirus software was initially evolved to identify and eliminate PC infections, thus the name. Be that as it may, with the expansion of different sorts of malware, antivirus software began to give security from other PC dangers.

Answer:
Following are the answer to this question:
Explanation:
In option 1:
The value of n is= 7, which is (base case)

when n=k for the true condition:

when n=k+1 it tests the value:

since k>6 hence the value is KH>3 hence proved.
In option 2:
when:
for n=1:(base case)

0<=0 \\ condition is true
when the above statement holds value n=1
when n=k

when n=k+1


![[\therefore KH>K \Rightarrow \log(KH>\loK)]](https://tex.z-dn.net/?f=%5B%5Ctherefore%20KH%3EK%20%5CRightarrow%20%20%5Clog%28KH%3E%5CloK%29%5D)
In option 3:
when n=1:

when n=k

hence n=k+1 is true.
<span>To give your app users the ability to open your app directly from other apps by clicking a link, you should use: deep link. With the deep link and its URL functionality, existing app users are driven directly inside the mobile app itself.
</span>Deep links are usually made up of two parts: a scheme (part of the link that identifies which app to open).<span>and a </span>host and path (<span>the unique location in the app where your content exists).</span>
