Which Statement Accurately Describes a Similarity or Difference in the Way

Which statement accurately describes a similarity or difference in the way acoustic speech and visual sign languages are perceived?

A) Vocally produced sounds vary in several acoustic dimensions, whereas only the shape of a hand gesture matters in sign language.
B) Experienced listeners of spoken language can ignore sound variations, whereas even those fluent in sign language never learn to ignore variation in hand shape.
C) Speakers acquire the accent of their communities, whereas signers produce universally stereotyped hand movements and shapes no matter where they use sign language.
D) There are no major differences-visual perception shares many principles with auditory perception, and both types of language function in an equally complex manner.
