Solution

The correct option is D Up - Geography
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.
$? - \to$ Finding Nemo $\to$ History
The one who likes Cars has a presentation on Biology.
$? - \to$ 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
$\begin{matrix} F r i e n d s & A n i m a t e d M o v i e s & P r e s e n t a t i o n S u b j e c t L & R i o & - M & - & P h y s i c s N & - & - O & L i o n K i n g & - P & - Q & - & C i v i c s R & - & - \end{matrix}$
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,
$R \to C a r s \to B i o l o g y$
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 presentation on English.
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:-
$\begin{matrix} F r i e n d s & A n i m a t e d m o v i e s & P r e s e n t a t i o n s u b j e c t s L & R i o & E n g l i s h M & F r o z e n & P h y s i c s N & U P & G e o g r a p h y O & L i o n K i n g & C h e m i s t r y P & F i n d i n g N e m o & H i s t o r y Q & S h r e k & C i v i c s R & C a r s & B i o l o g y \end{matrix}$

Now, we solve the following questions as,
Up - Geography combination is correct.
