Redox reaction

I couldn't find links to discussion about Redox reactions, so here I am, posting a redox reaction question under the general science board.
Can someone help me out with the question shown in the picture, what is the relationship between losing and gaining electrons with losing and gain H+ (H atom)?

Gaining an H atom does not mean gaining an H+ ion since an H atom still has an e-; this is an important distinction to make because when that new H atom is gained, its one e- will spend more time around the central atom it bonded to because it is more electronegative, and thus, that central atom is said to be reduced (reduction is gain of e-)

by the same token, gaining an H+ ion will not reduce (or oxidize for that matter) the molecule since there has been no change in the number of electrons
