It is given that
- $\text{Avinash} > \text{Abhay}$
- $\text{Vinay} > \text{Bharat} > \text{Vinu}$
Now come to Options
1. $\text{Vinay}$ is taller than $\text{Avinash}$ and $\text{Abhay}$ is taller than $\text{Bharat}.$
$\quad \implies$If we add $\text{Vinay}$ is taller than $\text{Avinash}$, then it will complete our purpose of getting tallest person - i.e., $\text{Vinay}$ is tallest.
2. $\text{Avinash}$ is taller than $\text{Vinay}$.
$\quad \implies$ It also complete our purpose. Because we can see then $\text{Avinash}$ is tallest now.
3. $\text{Abhay}$ is shorter than $\text{Vinay}$.
$\quad \implies$ This will not help you to get the tallest person, Because you can not understand that which one is tallest either $\text{Vinay}$ or $\text{Avinash}$.
4. None of these.
$\quad \implies$ This can not be the answer, because options $(1)$ and $(2)$ already help us to get the result.
Final Answer: Since in the question minimal set of information is mentioned, option B will be the answer.
