Correct option is B
From the given statement following Venn diagram can be drawn-

Analyzing the Options:
Let's evaluate each option based on the statements.
(a) Some tea are not snakes but they are pizzas.
Since some pizzas are tea, it's possible that there are pizzas that are not snakes. This option can be concluded.
(b) All pizzas are either tea or snakes.
We know that some pizzas are tea, and all snakes are pizzas, but we cannot conclude that all pizzas are either tea or snakes, as some pizzas may exist that are neither. Thus, this option cannot be concluded.
(c) Some pizzas are neither tea nor snakes.
Given that some pizzas are tea, and all snakes are pizzas, it's possible for some pizzas to be neither. This option can be concluded.
(d) Some tea are both pizzas and snakes.
Since we know that some snakes are tea and all snakes are pizzas, this option can also be concluded.
Conclusion: The option that CANNOT be concluded from the statements is (b) All pizzas are either tea or snake.
