Transfer RNA (tRNA) is an important type of RNA molecule involved in protein synthesis. It carries amino acids to the ribosome during protein synthesis and has an anticodon sequence that base pairs with the codon sequence of mRNA. However, tRNA is not transcribed from DNA in the nucleus. Instead, tRNA is transcribed from DNA in the nucleus and then undergoes extensive processing, including cleavage and modification, before it becomes functional. tRNA is also not the smallest type of RNA molecule; that title goes to microRNA (miRNA). Hence option 3 is the correct answer.
