Final answer:
Tacit knowledge is not easily codified or transferred, cannot be formulas or definitions, and is best acquired through informal learning.
Step-by-step explanation:
Tacit knowledge refers to the shared and accumulated knowledge, beliefs, assumptions, values, and technical knowledge that are passed on from one individual to another through the use of learned symbols, such as speech and writing. It is not easily codified or transferred from person-to-person, which means option 1) It is easily codified and transferred from person-to-person is not true.
Formulas and definitions are examples of explicit knowledge, not tacit knowledge. Tacit knowledge is more about experience, skills, and practical knowledge, rather than explicit information. Therefore, option 2) Formulas and definitions are examples of tacit knowledge is not true.
Tacit knowledge is best acquired through informal learning. It is acquired through hands-on experience, observation, and practice, rather than formal training and development. Therefore, option 3) It is best acquired through formal training and development is not true. The correct answer is option 4) It is best acquired through informal learning.
