1) Both — both Geiger-Müller counters and scintillation counters produce amplified electrical pulses that indicate the presence of ionizing particles (GM via avalanche in the tube, scintillation via scintillator + photomultiplier).
2) Scintillation counter — scintillation detectors (with appropriate crystals/PMT and spectroscopy or pulse-shape/energy discrimination) can distinguish alpha vs beta; GM tubes generally cannot discriminate particle type by pulse size.
3) Neither — this describes photographic film dosimetry (film badge), not a Geiger or scintillation counter.
4) Neither — individual cumulative monitoring is done with dosimeters (film badges, TLDs, electronic personal dosimeters), not with Geiger or scintillation counters.
