. Find out the alternative which will replace the question mark (?)Safe : Secure :: Protect : ? (a) Lock (b) Sure (c) Guard (d) Converse

The question is an analogy question. In these types of questions, you have to identify the relationship between the first two words and then find the word that has the same relationship with the third word.

Here, the relationship between "Safe" and "Secure" is that they are synonyms, meaning they have the same or nearly the same meaning.

So, we need to find a word that is a synonym of "Protect". Looking at the options:

(a) Lock - This is not a synonym of "Protect". It's related, but not the same. (b) Sure - This is not related to "Protect" at all. (c) Guard - This is a synonym of "Protect". They both mean to keep safe from harm or danger. (d) Converse - This is not related to "Protect" at all.

So, the correct answer is (c) Guard.
