The correct option is D one
A numeral adjective is an adjective that tells us about how many or how much or in what order the noun is. Definite numeral adjectives are ones which use cardinal (numbers used in an amount) and ordinals (numbers used as an order). 'One' is the cardinal number. Options A, B and C are emphasizing adjectives. Option E is an indefinite pronoun. Thus, option D is the correct answer.
