Which of the following describes a handle (as applicable to LR-parsing) appropriately?
- a)It is the position in a sentential form where the next shift or reduce operation will occur.
- b)It is a non-terminal whose production will be used for reduction in the next step.
- c)It is a production that may be used for reduction in a future step along with a position in the sentential form where the next shift or reduce operation will occur.
- d)It is the RHS of production p that will be used for reduction in the next step along with a position in the sentential.

Which of the following describes a handle (as applicable to LR-parsing...
Answer:
In LR-parsing, a handle refers to a substring of the input string that matches the right-hand side (RHS) of a production. It represents a potential reduction step in the parsing process. Among the given options, option 'D' accurately describes a handle.
Explanation:
To understand why option 'D' is the correct answer, let's break down the components of a handle and how it relates to LR-parsing.
1. Handle as the RHS of a production:
A handle is a substring that matches the RHS of a production rule. The RHS of a production rule represents the right-hand side of a production, which consists of terminals and non-terminals. The handle is the part of the sentential form that can be reduced according to the production rule.
2. Reduction in the next step:
The handle is used for reduction in the next step of the parsing process. Reduction involves replacing the handle with the non-terminal on the left-hand side (LHS) of the production rule. This process reduces the size of the sentential form and moves closer to the final parse tree.
3. Position in the sentential form:
The handle is associated with a position in the sentential form. It represents the location where the handle occurs in the sentential form, indicating where the next shift or reduce operation will occur. This position is important for determining the correct production rule to apply during reduction.
Considering these points, option 'D' correctly describes a handle as the RHS of a production that will be used for reduction in the next step, along with a position in the sentential form where the next shift or reduce operation will occur.
