Look specifically for 'Symbol' surrounded by two 'Letters'. Scan the sequence for patterns like (Letter)-(Symbol)-(Letter) and ignore numbers or consecutive symbols.

Analyze the Sequence
The sequence is: J, @, €, *, Y, %, V, %, C, I, D, %, D, H, $, K, ©, L, E, £, M, C. We need to identify symbols preceded and followed by letters (L-S-L).
Scan and Identify Triplets
Scanning from left: 1) Y-%-V (Yes), 2) V-%-C (Yes), 3) C-%-D (Wait, C-I-D has no symbol), 4) D-%-D (Yes), 5) D-H-(Wait,D−His letters),let′sre−verify:H−-K (Yes), K-©-L (Yes). Re-scanning: J(@), €(*), Y(%V), V(%C), C(I)D, (%), D(H),K(c◯)L,E(£)M...Total verified:Y%V,V%C,D%D,D%H(incorrect),let′slook carefully:Y%V,V%C,C%D,D%Hisnotasymbol,HK, K©L, E£M. That's 6 symbols.
A: 8 is incorrect; the sequence does not contain enough symbols meeting the criteria. B: 7 is incorrect based on the manual count. C: 5 is incorrect as it misses the 6th valid triplet.
D is correct because there are exactly 6 symbols (%, %, %, %, $, ©) that are immediately preceded and followed by a letter in the given sequence.
In alphanumeric series, always break the sequence into small overlapping triplets (3 elements) to avoid missing mid-sequence patterns.
