Panchromatic and multispectral sensors differ in that:

Correct option is C

· Panchromatic sensor:
· 1 broad band (usually 0.5–0.8 µm)
· High spatial resolution
· Multispectral sensor:
· Multiple narrow bands (e.g., red, NIR, green, SWIR)
· Lower spatial resolution
Why other options are wrong
· (a) Opposite of correct.
· (b) Multispectral has several bands, not one.
· (d) They differ in resolution & spectral width.
