possibility
2.

Facebook users.​

Answer 1

Answer:

1

Explanation:

2 is not available and acceptable

Answer 2

Both conclusions do not follow.

• This is a question based on syllogism and we need to solve it using venn diagram( attached below).

• As stated, all WhatsApp users are night. So they are related.

• Next, since night has a total negative relation with Facebook users, WhatsApp users will be sharing the same relation with Facebook users.

So, some WhatsApp users can never be Facebook users( Conclusion 2 is wrong).

• Also, as day shares some negative relation with Facebook users, it shares some negative relation with night as well( as No night is Facebook user= No Facebook users are night).

Therefore, all day cannot be night( Conclusion 1 is wrong).
