44. A pulse is applied to each input of a 2 input NAND gate. One pulse goes HIGH at t = 0 and goes back low at t = 1 ms. The other pulse goes HIGH at t = 0·8 ms and goes back low at t = 3 ms. The output pulse can be described as follows—

1. 1. It goes LOW at t = 0 and back HIGH at t = 3 ms

   
   
   

   2. It goes LOW at t = 0·8 ms and back HIGH at t = 3 ms

   
   
   

   3. It goes LOW at t = 0·8 ms and back HIGH at t = 1 ms

   
   
   

   4. It goes LOW at t = 0·8 ms and back LOW at t = 1 ms
