Explanation

'To gain' uses the infinitive form to express purpose - one works hard with the aim/purpose of acquiring knowledge. 'For gaining' uses a gerund which is less direct, 'to the gaining of' is overly wordy, and 'and gained' creates a compound predicate that doesn't convey purpose. Infinitive of purpose is most natural.
