Option (4) is Correct Option.
When environmental conditions are optimal, germination is initiated by a process termed Water Imbibition. The seed absorbs water through a structure called a micropyle, which induces swelling of the seed until it splits open.

During germination, seeds absorb water by imbibition. Thus, the correct answer is option (4) Imbibition.
Explanation:
- The germinating seeds only imbibe the water into their cells which is termed imbibition.
- Imbibition is the process of water take up by germinating seeds via absorption through the surface which results in its swelling.
- All the organic substances are arrested in a certain stage in all seeds which resume growth upon imbibitions of water, thus ruling out the chance of occurrence of any other form of water uptake.
