चौरस पूर्ण करण्यासाठी प्रश्न चिन्हाच्या ठिकाणी नसलेल्या वर्णाक्षरांचा संच निवडा :
S ? V O
W T ? S
O L ? K
X ? A T

The correct answer is Option B (P, Z, R, U).

Key Points:
• The correct option is (2).
• Let us examine the alphabetical positions (A=1, B=2, ..., Z=26):
• Row 1: S(19), ?(P=16), V(22), O(15) → Sum = 19 + 16 + 22 + 15 = 72.
• Row 2: W(23), T(20), ?(Z=26), S(19) → If ? is Z(26), sum = 88.
• Row 3: O(15), L(12), ?(R=18), K(11) → If ? is R(18), sum = 56.
• Row 4: X(24), ?(U=21), A(1), T(20) → If ? is U(21), sum = 66.
• Checking vertical pairs/differences or symmetric logic:
• Looking down columns or row relationships:
• Row 1: S(19) - 3 = 16 (P); V(22) - 7 = 15 (O)
• Row 3: O(15) - 3 = 12 (L); R(18) - 7 = 11 (K) -> perfectly follows (-3, -7) pattern! Here Row 1 has -3, then second half -7. Row 3 has O-3=L, and 18-7=11 (R and K).
• Row 2: W(23) - 3 = 20 (T); and with Z(26), 26 - 7 = 19 (S)! Perfectly matches (-3, -7)!
• Row 4: X(24) - 3 = 21 (U); and A(27) - 7 = 20 (T)! Perfectly matches (-3, -7)!
• Therefore, the missing letters across Rows 1 to 4 are: P, Z, R, U.
• This directly corresponds to option (2).
• Key Takeaway: The pattern follows letter positions where Column 2 = Col 1 minus 3, and Col 4 = Col 3 minus 7, giving P, Z, R, U.
