Multiple choice

Which of the below is operator precedence?

  1. $\epsilon + \epsilon + \dfrac{T}{T}$
  2. $\epsilon \rightarrow \epsilon + \epsilon $
  3. $\epsilon \rightarrow T $ $T\rightarrow T + \dfrac{T}{\epsilon}$
  4. $\epsilon \rightarrow \epsilon + \dfrac{T}{T}$ $\epsilon \rightarrow \dfrac{e}{id}$ $\epsilon \rightarrow \epsilon + \dfrac{T}{T}$

D Correct answer
Explanation

Option D shows productions with proper operator precedence structure (epsilon → epsilon + T/T, epsilon → e/id, etc.). The fraction notation and epsilon productions indicate precedence relations between operators.
