Among the given triad of terms, identify the triad in which the terms are…

To identify the triad in which the terms are similar to each other, we need to analyze the relationship between the letters in each pair.

Pattern Analysis
Let's look at the alphabetical positions (A=1, B=2, ..., Z=26) to see if there is a consistent gap between the letters in the pairs.

Option 1: RT - MO - BD

RT: 18, 20 (Gap +2)

MO: 13, 15 (Gap +2)

BD: 2, 4 (Gap +2)

Result: All pairs follow the same "+2" gap pattern. This is a consistent triad.

Option 2: AC - NP - JK

AC: 1, 3 (Gap +2)

NP: 14, 16 (Gap +2)

JK: 10, 11 (Gap +1)

Result: Inconsistent.

Option 3: YZ - CD - MT

YZ: 25, 26 (Gap +1)

CD: 3, 4 (Gap +1)

MT: 13, 20 (Gap +7)

Result: Inconsistent.

Option 4: JD - RT - OS

JD: 10, 4 (Gap -6)

RT: 18, 20 (Gap +2)

OS: 15, 19 (Gap +4)

Result: Inconsistent.
