Question

Which of the following virus species will grow together in solution (x1), if no other virus species or catalyst is present in the solution?

• A. Beetal and Dena
• B. Beetal and Cheek
• C. Ante and Dena
• D. Ante and Cheek

Answer 1

The correct option is A Beetal and Dena

Cheek requires the presence of catalyst X to grow in solution (x1).
$\therefore$ Option (b) and (d) can be eliminated.
From condition (I), we can see that Ante and Dena cannot grow together.
$\therefore$ Option (c) is also eliminated.
From condition(IV) we get that virus Dena can grow in the solution even if not other virus species or catalyst is present in the solution.
From condition (II) we get that virus Beetal can grow in the solution (x1) only if Dena is present.
$\therefore$ Option (a) does not violate any of the give conditions.
