How can one know which path among karma, bhakti and jnana are suitable for him?

The answer is simple. Just ask yourself:

How attached am I to this material life?
How much material desire do I have?
Do I like the life experience here?

Depending upon your answers and how you feel about them, you can easily decide which path is suitable for you. Because the scripture says the following:

nirviṇṇānāṁ jñāna-yogo nyāsinām iha karmasu
teṣv anirviṇṇa-cittānāṁ karma-yogas tu kāminām
[SB - 11.20.7]

Among these three paths, jñāna-yoga, is recommended for those who are disgusted with material life and are thus detached from ordinary, fruitive activities. Those who are not disgusted with material life, having many desires yet to fulfill, should seek path of karma-yoga.

yadṛcchayā mat-kathādau jāta-śraddhas tu yaḥ pumān
na nirviṇṇo nāti-sakto bhakti-yogo ’sya siddhi-daḥ

[SB - 11.20.8]

Meaning
If somehow or other by good fortune one develops faith in hearing and chanting My glories, such a person,....

....being neither disgusted with nor very much attached to material life, should achieve perfection through the path of loving devotion to Me.

So the rule is simple:
1) If you are not interested in material life, then follow path of jnana (dhyana is primary part of it)

2) If you are attached to material life and have material desires without much interest in God and spiritual things, then follow the path of Karma.

3) If you are neither too detached, nor too attached and have faith and interest in God, then follow the path of bhakti.

Irrespective of which path you follow, if you do it properly, then it will automatically lead you to the other. However, in this present age of Kali, following the path of jnana is very difficult. And bhakti (devotion to God) gives the result of all the other paths.

So ask yourself those questions and depending upon your state of mind you can easily decide which path is suitable for your current situation.
