In GCM, we define S as S = GHASH(A||0v||C||0u||[len(A)]||[len(C)]). What is u defined as?

a) 64 ceil[len(A)/128] – len(A)
b) 64 ceil[len(C)/128] – len(C)
c) 128 ceil[len(A)/128] – len(A)
d) 128 ceil[len(C)/128] – len(C)
b) 64 ceil[len(C)/128] – len(C)
c) 128 ceil[len(A)/128] – len(A)
d) 128 ceil[len(C)/128] – len(C)
