The correct answer is: C. 16 bit word size, 16 bit data path.
The 8088 CPU has a 16-bit word size, which means that it can process data in 16-bit chunks. It also has a 16-bit data path, which means that it can transfer data between itself and memory in 16-bit chunks. This makes it a relatively powerful CPU for its time.
The other options are incorrect because they do not match the actual specifications of the 8088 CPU. Option A is incorrect because the 8088 CPU has a 16-bit word size, not an 8-bit word size. Option B is incorrect because the 8088 CPU has a 16-bit data path, not an 8-bit data path. Option D is incorrect because the 8088 CPU has a 16-bit word size, not a 4-bit word size. Option E is incorrect because the 8088 CPU has a 16-bit data path, not an 8-bit data path.
