Answer 1

The correct option is D Other than those given as options

Seven friends L, M, N, O, P, Q and R like different animated movies and they have a presentation on different topics.
The one who likes Finding Nemo has a presentation on History.
$\underset{–}{?}\to$ Finding Nemo $\to$ History
The one who likes Cars has a presentation on Biology.
$\underset{–}{?}\to$ Cars $\to$ Biology.
P does not like UP. M does not like UP.
Q does not like UP, R does not like UP.
O likes Lion King and L likes Rio.
R does not have a presentation on History.
R does not like Finding Nemo. The one who likes UP does not have a presentation on Chemistry. M has a presentation on physics.
Q has a presentation on Civics.
Now, according to above inforamtion, we get
$\begin{array}{ccc}Friends& AnimatedMovies& PresentationSubject\\ L& Rio& -\\ M& -& Physics\\ N& -& -\\ O& LionKing& -\\ P& -& \\ Q& -& Civics\\ R& -& -\end{array}$
We note that P, Q, R, and M do not like UP.
So, N likes UP. $N\to$ UP.
Only two friend P and R available and R does not have a presentation on History,
So,
$R\to Cars\to Biology$
and $P\to$ Finding Nemo $\to$ History
Only two animated movies are left and Q does not like neither Frozen nor UP.
So, Q like Shrek.
$Q\to$ Shrek $\to$ Civics
And $M\to$ Frozen $\to$ Physics
L has a presentation neither on Geography nor on Chemistry.
So, L has a presentaion on Engilsh.
N likes UP and the one who likes up does not have a presentation on Chemistry.
So, $N\to$ Up $\to$ Geography and O is the only one one that left. So O has a presentation on Chemistry. Now, we arrange the following information in tabular from as:-
$\begin{array}{ccc}Friends& Animatedmovies& Presentationsubjects\\ L& Rio& English\\ M& Frozen& Physics\\ N& UP& Geography\\ O& LionKing& Chemistry\\ P& FindingNemo& History\\ Q& Shrek& Civics\\ R& Cars& Biology\end{array}$

Now, we solve the following questions as,
P has a presentation on History.
