How do property rights benefit entrepreneurs?

a) by enabling them to purchase capital and use it as they see fit
b) by allowing them to use their employees’ property
c) by facilitating the use of public property for private businesses
d) by freeing unused public land for commercial purposes
e) by letting them display advertisements on public property

I believe the answer is:  by enabling them to purchase capital and use it as they see fit

Because of property rights, the only person who has the full right to use the property would be the legal owner whose name is written in the purchase agreement and use it for his/her own purpose.
Without this, other individuals could claim ownership to the properties and the true owner wouldn't be able to reclaim it with the help of legal establishment.
