Scan the sequence for numbers (digits) and check the exact character immediately to its left and right. Look for [Symbol] [Number] [Symbol] triplets.
Step 1: Understand the Condition
We need to find numbers that satisfy the pattern: [Symbol] тЖТ [Number] тЖТ [Symbol] (counting strictly from left to right).
Step 2: Scan the Series
Series: @ 2 # 2 4 3 = % 8 * 1 8 @ $4! 6 4 3 * 8 =. Checking each number from left to right for preceding and succeeding symbols.
Step 3: Identify Valid Triplets
Step 4: Count and Conclude
Total number of such valid occurrences is 4. Thus, Option C is correct.
A: Three is incorrect because exactly four valid triplets exist. B: One is incorrect as multiple valid symbol-number-symbol combinations are present. D: Five is incorrect since a rigorous left-to-right scan yields exactly four matches.
Option C is correct because there are exactly four numbers in the given series that are immediately preceded and followed by a symbol (@ 2 #, = 8 *, @ 8 $,! 3 *).
