Answer:
B). “Tingling” and “tinkling” suggest sweet, sentimental memories of childhood.
Step-by-step explanation:
'Piano' by D. H. Lawrence discusses an adult recollecting his childhood memories through the music which is here symbolized by 'piano'(functioning as a metaphor). A woman plays the piano and sings along which takes the poet back to his childhood where he(the poet) supposes himself to be a 'A child sitting under the piano, in the boom of the tingling strings.' Later, the 'tinkling' of piano guides him towards his happy, warm, and cheerful past. Thus, the 'tingling' and 'tinkling' of piano most aptly propose the sweet and affectionate recollections of his childhood days. Therefore, option B is the correct answer.
