The correct answer is:

b) Tumour suppressor proteins lose regulation when mutated, leading to oncogenesis

Here's why:

Tumour suppressor proteins are a type of protein that regulates cell division and prevents the formation of tumours. They work by slowing down cell division, repairing DNA mistakes, or telling cells when to die (a process known as apoptosis or programmed cell death).

When these proteins are functioning correctly, they help keep cell growth and division in check. However, when these proteins are mutated, they can lose their ability to regulate cell growth and division. This can lead to uncontrolled cell growth, a hallmark of cancer. This process is known as oncogenesis.

So, the statement "Tumour suppressor proteins lose regulation when mutated, leading to oncogenesis" is correct. The other options are incorrect because tumour suppressor proteins do not become hyperactive when excited by cell signalling factors, they do not normally function to stimulate cell growth and division, and while they do prevent unneeded cell division, this is not the only function they serve.
