C is purely functional and imperative language .

Hence, option B is correct.

---

So, why option B, why not D ?

---

@vijaycs,

There is difference between purely functional and funtional .

Like C++ is object oriented and not purely object oriented .

---

yes , diff between purely object oriented and object oriented is okay,

But, please check this,

https://en.wikipedia.org/wiki/List_of_programming_languages_by_type#Functional_languages

 Many so-called functional languages are "impure", containing imperative features

---

I guess they have given so, because  C can be made functional explicitly but this feature is not by default in C. Like, LISP has implicit functional properties.

@Arjun sir, please check above wiki reference, sir .

C is procedured , structured language . not functional , declarative

C is not purely functional language as here we dont write program base on functional logic

---

@Arjun sir wiki page https://en.wikipedia.org/wiki/Functional_programming says that it is a declarative programming paradigm. So if C is functional then it should be declarative according to this. I am confused.

---

Here also C is not in the list of functional programming. More ever the related paradigm to functional programming is given as declarative.
https://en.wikipedia.org/wiki/Comparison_of_programming_paradigms#Main_paradigm_approaches

---

Well, it is ambiguous. As per current convention, no one will call C as a functional language. This will never be asked in GATE at least. Is a bad question for GATE.

Answer 2

i think the answer should be (d) s1,s3,s4.

because  c is completly functional and procedure language . And their is also a structure facility .

Answer 3

Ans: D
