The correct answer is option 'c) 1, 3, 4 and 5'. Let's understand the immediate hazardous effects of an earthquake in detail:

1. Ground Shaking:
- Ground shaking is the primary and most obvious immediate effect of an earthquake.
- It occurs due to the release of seismic energy from the Earth's crust, causing the ground to vibrate.
- The intensity of ground shaking depends on the magnitude of the earthquake, distance from the epicenter, and local geology.
- Ground shaking can result in the collapse of structures, damage to infrastructure, and injury or death to people.

2. Soil Liquefaction:
- Soil liquefaction is a phenomenon that occurs in loose or saturated soil during an earthquake.
- The shaking of the ground causes the soil to lose its strength and behave like a liquid temporarily.
- This can lead to the sinking or tilting of structures, including buildings and bridges, which are built on such soil.
- Soil liquefaction can cause significant damage to infrastructure and endanger lives.

3. Fires:
- Earthquakes can trigger fires in various ways, making them another immediate hazardous effect.
- Gas lines may rupture, causing leaks and subsequent fires.
- Electrical lines may be damaged, leading to short circuits and fires.
- Buildings and structures may collapse, resulting in damaged gas and electrical systems, which can ignite fires.
- Fires can quickly spread and cause additional destruction to property and lives.

4. Avalanches:
- Earthquakes can trigger avalanches in mountainous regions, particularly in areas with significant snow accumulation.
- The shaking of the ground can dislodge snow from slopes, leading to a rapid descent of snow masses.
- Avalanches can bury structures, block roads, and pose a threat to human life and livestock in the affected areas.

5. Tsunami:
- Tsunamis are large ocean waves generated by undersea earthquakes or volcanic eruptions.
- When an earthquake occurs under the ocean floor, it displaces water, creating a series of powerful waves.
- These waves can travel across long distances and reach coastal areas, causing widespread devastation.
- Tsunamis can result in flooding, destruction of coastal infrastructure, and loss of life.

In conclusion, the correct answer is option 'c) 1, 3, 4 and 5' as ground shaking, fires, avalanches, and tsunamis are all immediate hazardous effects of an earthquake. It is important to be aware of these potential dangers and take appropriate measures to mitigate their impact.
