Each diagram shows a stationary wave on a stretched string. Which diagram is correctly labelled?

stationary wave diagram A: a solid curve and a dashed curve (the string at two different times) trace two full loops; the label 'node' points to the peak of the first solid crest and the label 'antinode' points to the crossing point between the two loops; the wavelength bracket underneath spans only the first loop

stationary wave diagram B: a solid curve and a dashed curve trace two full loops; the label 'antinode' points to the peak of the first solid crest and the label 'node' points to the crossing point between the two loops; the wavelength bracket underneath spans only the first loop

stationary wave diagram C: a solid curve and a dashed curve trace two full loops; the label 'node' points to the peak of the first solid crest and the label 'antinode' points to the crossing point between the two loops; the wavelength bracket underneath spans both loops, from the left end of the pattern to the right end

stationary wave diagram D: a solid curve and a dashed curve trace two full loops; the label 'antinode' points to the peak of the first solid crest and the label 'node' points to the crossing point between the two loops; the wavelength bracket underneath spans both loops, from the left end of the pattern to the right end
