A. Steadfast
B. Persistent
C. Devious
D. Both a & b

Explanation:

The word aberrant means deviating from the normal, unusual, or not following the correct path or behavior.

In simple words: something or someone that behaves in an abnormal or irregular way.

The opposite of aberrant is something that is stable, regular, and consistent with normal behavior, which includes both steadfast and persistent.

So, both A & B are the correct answer.

Real-Life Example

Imagine two students:

• A student who keeps changing behavior, breaking rules, and acting strangely → this is aberrant behavior.
• A student who stays consistent, follows rules, and remains focused → this is steadfast/persistent behavior.

Irregular = Aberrant
Stable = Steadfast / Persistent

Main Points for Exams

• Aberrant means abnormal or deviating from the norm.
• It is often used in behavior, biology, or patterns.
• Steadfast and persistent mean stable and consistent.
• Devious is similar to aberrant, not opposite.
• Therefore, both A & B are the correct answer.
• This type of question is common in PPSC, FPSC, CSS, PMS, NTS, IELTS, TOEFL, and other competitive exams.
