In a certain code, BASIC is written as DDULE. How is LEADER written in that code?

NHCGGU

The correct answer is Option (1) → NHCGGU

Let's find the pattern from BASIC → DDULE:

• B → D : +2
• A → D : +3
• S → U : +2
• I → L : +3
• C → E : +2

So the letters are shifted alternately +2, +3, +2, +3, +2, ...

Apply this to LEADER (6 letters):

• L +2 → N
• E +3 → H
• A +2 → C
• D +3 → G
• E +2 → G
• R +3 → U

Result: NHCGGU
