In a certain code language, COULD is written as BNTKC and MOULDING be written in the same code language, how will moulding be written in that language? (a) LNKTCHMF (b) LNKICHMF (c) LNTKCHMF (d) None of these.

The problem states that "COULD" is written as "BNTKC". Let's find the relationship between each letter in the original word and its coded counterpart.
C $\to$ B (C is the 3rd letter, B is the 2nd letter; B is the letter before C)
O $\to$ N (O is the 15th letter, N is the 14th letter; N is the letter before O)
U $\to$ T (U is the 21st letter, T is the 20th letter; T is the letter before U)
L $\to$ K (L is the 12th letter, K is the 11th letter; K is the letter before L)
D $\to$ C (D is the 4th letter, C is the 3rd letter; C is the letter before D)
The pattern is that each letter in the original word is replaced by the letter immediately preceding it in the English alphabet (a shift of -1).

We need to find how "MOULDING" will be written using the same coding pattern.
M $\to$ L (M - 1 = L)
O $\to$ N (O - 1 = N)
U $\to$ T (U - 1 = T)
L $\to$ K (L - 1 = K)
D $\to$ C (D - 1 = C)
I $\to$ H (I - 1 = H)
N $\to$ M (N - 1 = M)
G $\to$ F (G - 1 = F)

The coded word for "MOULDING" is LNTKCHMF.
Now, let's check the given options:

(b) LNKTC HMF

(c) LNTKCHM

(e) None of these

Our derived code LNTKCHMF does not exactly match option (b) (which has K instead of T for the third letter) or option (c) (which is missing the final F).

Therefore, the correct option is (e).

The final answer is $\boxed{\text{e) None of these}}$
