Compact soil, rocks, buried debris are all things that will impede root growth.
Yes, when roots encounter an obstacle preventing them from growing downward, they may begin to grow horizontally in search of space and nutrients. This phenomenon is known as root circumnavigation or root colonization and is a common adaptive response in plant roots.
Positive gravitropism, where the plant roots grow in response to gravity by growing downward. This helps the roots anchor the plant and seek out nutrients and water in the soil.
Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia
The main root in gymnosperms, eudicotyledons, and magnoliids, usually stouter than the lateral roots and growing straight downward from the stem. The taproot develops from the primary root. The taproot and its lateral roots penetrate deeper into the soil than the fibrous roots characteristic of monocotyledons.
When roots and stems grow in a specific direction due to environmental stimuli, it is referred to as "tropism." Roots typically exhibit positive gravitropism, growing downward in response to gravity, while stems often show negative gravitropism, growing upward. Additionally, plants can exhibit phototropism, where stems grow toward light.
The response of roots growing downward is an example of gravitropism, also known as geotropism. This is a plant's natural reaction to gravity where the roots grow towards the Earth to anchor the plant and absorb water and nutrients.
When roots are blocked from going random they just stop growing.

Roots of a growing bean seed plant will exhibit positive gravitropism, meaning they will grow downward in response to the force of gravity. This allows the roots to anchor the plant into the soil and seek out nutrients and water necessary for growth.

Downward
They spread out so they cover a greater surface area. This means they can take in more water.
Of the four choices - 'it stops growing' is false. Even in winter - trees still continue to grow (though at a drastically reduced rate). That's what creates the 'rings' you see when you cut off a branch.
The answer is yes because once blocked by something where else does the root have to go but everywhere! So yes, roots grow in random directions when blocked.

Is gravitropism why the seed is growing towards gravity?Yes gravitropism is why the roots go towards the center of the Earth.
Geotropism is the term used to describe a plant's roots growing downward in response to gravity. This is a common plant behavior that helps roots penetrate deeper into the soil for better anchorage and access to water and nutrients.
