Question

If in a certain code CRYSTAL is written as DTJSXFR, then in the same code how is QUANTUM written?

• A. WRDNXZS
• B. RWDNYZS
• C. RWDNXZS
• D. RWNDXZS

Hint:

For coding sequences, look for a fixed per-position shift pattern by comparing the sample input and output letter by letter.

Answer 1

The Correct Option is C

Step 1: From \(\text{CRYSTAL}\to\text{DTJSXFR}\), positions shift by \(+1,+2,+3,+0,+4,+5,+6\).

Step 2: Apply the same shifts to \(\text{QUANTUM}\): \(Q{+}1{=}R,\ U{+}2{=}W,\ A{+}3{=}D,\ N{+}0{=}N,\ T{+}4{=}X,\ U{+}5{=}Z,\ M{+}6{=}S\).

Step 3: Reading these off in order gives the coded word.
\[ \boxed{\text{RWDNXZS}} \]
