Answer:
B. Intangible resources
Step-by-step explanation:
A resource refers to something capable of yielding current or future benefit to an individual or an organization.
Those resources which cannot be perceived or which do not have any physical substance, are referred to as intangible resources.
Intangible resources are valued based upon the expected future economic benefits that they yield.
Examples of intangible assets would be, copyrights, patents, trademarks, brand etc.
As per the given case, culture, knowledge, brand equity, reputation and trade secrets can all be classified as tangible resources since these cannot be felt or perceived, devoid of physical existence and would yield future economic benefits to the ones who possess them.
