Samas (Compound Words)

Looking at "mata-pita" (mother-father), Karan thinks it means "a father like a mother" — one word describing the other. His sister says both words are equal here. Who is right?

Looking at "neelkamal" (blue lotus), Aisha thinks it is like "mata-pita" — two equal things joined by "and", meaning "blue and lotus". Her brother says one word describes the other here, not equality. Who is right?

Naina thinks every compound has one word describing the other, as in "neelkamal". With this thinking, she tries to read "bhai-behen" (brother-sister) the same way — "a sister like a brother". Her friend says both words are equal here too. Who is right?

Looking at "pitambar", Vishal thinks it simply means "yellow cloth" — a describing compound like "neelkamal". His teacher says the word actually points to someone else entirely. Who is right?
