The orange wave is A, green is B and blue is Y.
The C in CMOS stands for 'complimentary', because pairs of NMOS and PMOS are used to fabricate a CMOS circuit. This circuit is a NAND gate, which is a universal gate and can easily be fabricated using CMOS technology.
The truth table for a NAND gate is:
A         B         Y
0         0         1
0         1         1
1         0         1
1         1         0
A NAND gate's output is high as long as both of it's inputs are not 1, which is the opposite of an AND gate.
