Correct Answer: (b) the nearest large
Solution:'Superlative degree' denotes the form of an adjective or adverb that expresses the highest or a very high degree of quality of a thing, person etc. For example, most, best, worst, greatest, etc. However, we always place the definite article 'the' before any superlative adjective. In the given sentence we will use the superlative form after the definite article 'the'. Hence, 'the nearest large' is the most appropriate answer.
