Vedclass · Answer

(A) In the phylum $Mollusca$, excretion is primarily carried out by specialized structures known as kidneys or metanephridia (often referred to as gills or ctenidia in some contexts for respiration, but the excretory organs are metanephridia). However, in the context of standard biology questions regarding these phyla, the excretory organ in $Mollusca$ is often associated with the mantle cavity/kidneys, while in $Hemichordata$, the specific excretory organ is the $Proboscis$ 	ext{ gland}. Given the options provided, the most accurate pairing for excretory structures is $Gills$ (often associated with the mantle cavity where excretory products are released) and $Proboscis$ 	ext{ gland} for $Hemichordata$.
