**Question:** All of the following statements about 'Imbecile' are true, EXCEPT:

A. Imbecile refers to an individual with an intelligence quotient (IQ) between 50 and 70.
B. Intelligence is determined by multiple factors such as genetics and environment.
C. Imbecile is a term used to describe a person with significant developmental disabilities.
D. Imbecile is considered a synonym for mental retardation.

**Correct Answer: Option B.**

**Core Concept:** Mental retardation and intelligence are interrelated terms describing cognitive abilities and developmental potential. Intelligence is a broad concept influenced by various factors, including genetics, environment, and upbringing. IQ (Intelligence Quotient) is a commonly used measure of cognitive abilities.

**Why the Correct Answer is Right:**

Option B is correct because it is false that intelligence is determined solely by genetics. Intelligence is a complex trait influenced by multiple factors, including environment, social opportunities, and educational experiences. Intelligence is not a fixed trait but can be influenced by various life experiences, making the statement "intelligence is determined by genetics" incorrect.

**Why Each Wrong Option is Incorrect:**

A. Intelligence quotient (IQ) is indeed between 50 and 70 for individuals with imbecile, which indicates significant developmental disabilities and cognitive limitations. This option is correct.

C. Imbecile is indeed a term used to describe individuals with developmental disabilities, which are associated with limited cognitive abilities. This option is correct.

D. Imbecile is considered a synonym for mental retardation, which is a term no longer used due to its negative connotations. The correct term for individuals with IQ between 50-70 is "Mild Intellectual Disability" or "Mild Cognitive Impairment."

**Clinical Pearl:** The use of terms like "imbecile" and "mental retardation" should be avoided in clinical practice due to their negative connotations. Instead, we now use terms like "Mild Intellectual Disability" or "Mild Cognitive Impairment" to describe individuals with an IQ between 50-70. Understanding the nuances of these terms is crucial for providing appropriate diagnosis, treatment, and support to these individuals.
