The verb "to commend" means "to praise." Thus, a "commendation" is the actual praise that is received. For example, we might say that someone receives a commendation from the president of the United States for an important scientific breakthrough that will save many lives. Thus, the commendation is the actual praise that is given.  It is a bit of an abstract word, for "praise" is not something that we can really touch or see. However, we do often talk like it is: "She received the praise with grace."  Thus, someone could also say, "She received the commendation with grace and appreciation." Of the options given, only "recognition" is closest to this kind of praise. When we "recognize" someone, we often mean to call attention to that person and thus to praise him or her.

The word "deprivation" describes a particular state of being, namely that of being deprived. Now, "to be deprived" means to have something taken from oneself. For this reason, it is tempting to think that deprivation indicates something related to stealing or robbery. However, it really describes the state of having a lack as a result of any cause. For instance, "sleep deprivation" occurs when someone lacks sleep. Such sleep is unlikely to be described as being "stolen" (at least not literally). Thus, we can say that "deprivation" is a state of poverty—a state of lack. Poverty can refer not only to money but to any lack whatsoever, though we do usually use the word to indicate financial lack. Thus, the best option provided is "poverty."
