Concept:
The word \textit{recalcitrant} comes from the Latin \textit{recalcitrare}, meaning “to kick back.” It is commonly used to describe people who resist rules, control, or authority.
Explanation:
A \textit{recalcitrant} person is stubbornly defiant and refuses to obey instructions, discipline, or authority. The word is often used in contexts involving students, employees, or individuals who resist discipline or social norms.
For example:
\begin{itemize}
\item The recalcitrant student refused to follow the school rules.
\item The manager struggled to control the recalcitrant employee.
\end{itemize}
Option (A) is incorrect because someone easily persuaded is the opposite of recalcitrant.
Option (C) relates to intelligence, which is unrelated to obedience.
Option (D) refers to forgetfulness, which does not match the meaning of the word.
Therefore, option (B) correctly defines the term.
