The correct answer is C. Blends
Step-by-step explanation:
A consonant is any letter of the alphabet except by the vowels (a,e, i,o,u sounds) or semivowels (w, y), this means consonants include letters such as l, p, c, d, b, r, k, m or f. Consonants are also classified as voiced if the vocal cords vibrate when they are pronounced or voiceless if there is no vibration. Additionally, consonants can be combined, in this way, if two or even three voiced consonants are combined you create a "Blend", but if the consonants are voiceless then it is a "Diagraph". Examples of Blends include Bl, Fl, Cr, Dr, Pr and examples of Diagraphs are st, sh, wh. Thus, Bl, Cl, Br, and Cr are examples of a combination of voiced consonants or blends.
