Concept:
The IRS (Indian Remote Sensing) LISS-III sensor is a multispectral imaging instrument, so it is described by both its ground spatial resolution and the number of spectral bands it records.
Step 1:
The LISS-III sensor has a spatial resolution of about 23.5 m, commonly quoted as 23.00 m × 23.00 m for the pixel ground size. The finer 5.8 m resolution belongs to the panchromatic (PAN) sensor, not LISS-III.
Step 2:
LISS-III images in four spectral bands: green, red, near infrared and short wave infrared. Therefore the resolution is 23.00 m × 23.00 m and the number of bands is 4.
Answer: Option (3) — 23.00 m × 23.00 m and 4.
