Need help annotating IR spectrum peaks

Which of the the following is false regarding spectrophotometry?   A. The concentration of a sample increaes with the path length of the curvette or sample holder since the absorbance increases   B. When absorbance increases, transmittance decreases   C. The absorption coefficient depends on wavelength of light and type of sample   D. Materials with higher absorption coefficients more readily absorb light.   E. The lambda max of a red sample is at a shorter wavelength than the lambda max of a blue sample
