The correct answer is Option (2) → A, D and E only

A. He conceptualised three intelligences Correct. The triarchic theory has three basic types of intelligence: componential, experiential and contextual.

B. It was proposed in 1950. Incorrect. Robert Sternberg proposed the triarchic theory in 1985.

C. He defined intelligence as the ability to judge well, understand well and reason well. Incorrect. This is Alfred Binet’s definition. Sternberg views intelligence as ‘the ability to adapt, to shape and select environment to accomplish one’s goals and those of one’s society and culture’.

D. Componential intelligence also refers to the traditional notion of intelligence. Correct. Componential or analytical intelligence is the analysis of information to solve problems; persons high on it think analytically and critically and succeed in schools. This school-type ability is what intelligence has traditionally meant and what IQ tests measure.

E. Contextual intelligence refers to practical intelligence, known as ‘Street Smart’. Correct. Contextual or practical intelligence is the ability to deal with environmental demands met daily; it may be called ‘street smartness’ or ‘business sense’.

Note: It seems that there is a mistake in the original NTA paper, which prints ‘technical theory of intelligence’ when it should read ‘triarchic theory of intelligence’. Robert Sternberg proposed the triarchic theory, and statements A, D and E describe its three intelligences, so the intended reading is clear.
