Which one of the following is true of tRNAs?
a) tRNAs are double-stranded.
b) Each tRNA binds a particular amino acid.
c) There are four types of tRNA.
d) tRNAs carry special sequences known as codons.
e) All of the above

tRNA are single stranded just like most of the RNAs. Hence option A is incorrect. Due to the presence of specific L shaped structure, tRNAs bind specifically to only certain amino acids. Hence, option B is correct

There can be nearly 20 types of tRNAs based on the type of amino acids also their grouping can be done based on anticodon. Hence, on basis of amino acid, there can be 20 types of tRNAs. Hence, option C is correct

tRNAs carry anticodons that are made up of three nucleotides. Hence option D is also incorrect.

Option B is correct

Which one of the following is true of tRNAs? a) tRNAs are double-stranded. b) Each tRNA binds a particular amino acid. c) There are four types of tRNA. d) tRNAs carry special sequences known as codons. e) All of the above
