To determine the correct option, you only need to know the correct gender of the person who performs the action. In this case we are talking about the "hermano" and therefore the corresponding article is "el"

If an adjective ends in an "o," you change it to an __"a" before adding the adverbial ending.

For example:

rapido is an adjective ending in o, when you change it into an adverb you have; RAPIDAMENTE

pausado changes into pausamente

acelerado changes into aceleradamente

lento changes into lentamente
