Which one of the following is a trick used in Spanish to identify the right hand?

A common trick to identify the right hand in Spanish is to remember that "derecha" (right) has the letter "d," which can be associated with "derecho" (straight) or "d" for "dominant" hand. Additionally, many people use the mnemonic that the right hand is often the one that performs tasks like writing or eating, as it is traditionally the dominant hand for most individuals. This method can help reinforce the distinction between left ("izquierda") and right hands in everyday situations.
