1. A.

   With no propagation delays, the output 𝒀 is always logic Zero

2. B.

   With no propagation delays, the output 𝒀 is always logic One

3. C.

   With propagation delays, the output 𝒀 can have a transient logic One after 𝑿 transitions from logic Zero to logic One

4. D.

   With propagation delays, the output 𝒀 can have a transient logic Zero after 𝑿 transitions from logic One to logic Zero
