What is the mortality rate for pseudorabies in pigs under 1 month of age? a.45% b.90% c.25% d.10%

First Pseudorabies is also known as Aujeszky's disease it effects infant pigs respiratory system as well as their neurological system. 
My best answer would be B at 90% 
The reason being is that suckling pigs normally never live through pseudorabies. It use to be 100% mortality rate. . 
*hope this helps*
