Step-by-step Solution:

The coding pattern for DENMARK to FCPKCPM involves alternating +2 and -2 transformations for each letter, starting with +2.

Applying the same pattern to SINGAPORE:

• S (+2) → U
• I (-2) → G
• N (+2) → P
• G (-2) → E
• A (+2) → C
• P (-2) → N
• O (+2) → Q
• R (-2) → P
• E (+2) → G

The coded word is UGPECNQPG.

Answer: (A) UGPECNQPG
