Consider the following grammar. S → S#cS | SS | Sε | <S> | a | b | c The…

1. Rule 1: Start Symbol

   Since S is the start symbol, the end-of-input marker $ is always in Follow(S).

   • Follow(S) = {$}

2. Rule 2: S -> S#cS

   • Looking at the first S (before #), the terminal # follows S.

   • Looking at the second S (at the end), anything in Follow(S) is added to Follow(S) (no new terminals).

   • Follow(S) = {$, #}

3. Rule 3: S -> SS

   • For the first S, anything in First(S) is added to Follow(S).

   • From the productions, First(S) = {a, b, c, <}.

   • Follow(S) = {$, #, a, b, c, <}

4. Rule 4: S -> <S>

   • The terminal > follows S.

   • Follow(S) = {$, #, a, b, c, <, >}

Final Set and Cardinality

The complete set is Follow(S) = { $, #, a, b, c, <, > }.

The number of elements (cardinality) is 7.

Correct Option: 4
