To solve this problem, we need to understand the pattern used to convert the words into the coded language. We will do this by observing the conversion of 'PLAYER' to 'CNRSFZ' and 'LIQUID' to 'SKNEJV'. Let's break down this pattern:

1. The word 'PLAYER' is converted to 'CNRSFZ':
   • Convert each letter to its corresponding position in the alphabet:

P (16), L (12), A (1), Y (25), E (5), R (18)

• The coded letters 'CNRSFZ' correspond to:

C (3), N (14), R (18), S (19), F (6), Z (26)

• Notice the pattern for conversion:
  • P = 16 becomes C = 3: 16 + 3 = 19 -> 1 + 9 = 10 -> 1 + 0 = 1(C)
  • L = 12 becomes N = 14: 12 + 10 = 22 -> 2 + 2 = 4(N)
  • A = 1 becomes R = 18: 1 + 17 = 18(R)
  • Y = 25 becomes S = 19: 25 - 6 = 19(S)
  • E = 5 becomes F = 6: 5 + 1 = 6(F)
  • R = 18 becomes Z = 26: 18 + 8 = 26(Z)

1. The word 'LIQUID' is converted to 'SKNEJV':
   • Convert each letter to its corresponding position in the alphabet:

L (12), I (9), Q (17), U (21), I (9), D (4)

• The coded letters 'SKNEJV' correspond to:

S (19), K (11), N (14), E (5), J (10), V (22)

• Notice the pattern for conversion:
  • L= 12 becomes S = 19: 12 + 7 = 19(S)
  • I = 9 becomes K = 11: 9 + 2 = 11(K)
  • Q = 17 becomes N = 14: 17 - 3 = 14(N)
  • U = 21 becomes E = 5: 21 - 16 = 5(E)
  • I = 9 becomes J = 10: 9 + 1 = 10(J)
  • D = 4 becomes V = 22: 4 + 18 = 22(V)

Now apply this pattern to the word 'RECORD':

• Convert each letter to its position:

R (18), E (5), C (3), O (15), R (18), D (4)

• Apply a similar transformation as observed:
  • R = 18 becomes E: E = 5, where 18 - 13 = 5 (E)
  • E = 5 becomes G: G = 7, where 5 + 2 = 7 (G)
  • C = 3 becomes T: T = 20, where 3 + 17 = 20 (T)
  • O = 15 becomes E: E = 5, where 15 - 10 = 5 (E)
  • R = 18 becomes S: S = 19, where 18 + 1 = 19 (S)
  • D = 4 becomes P: P = 16, where 4 + 12 = 16 (P)

Thus, the word 'RECORD' is converted to: EGTESP.

Therefore, the correct answer is EGTESP.
