To solve this matching problem, we need to understand the functionality of each integrated circuit (IC) listed in List-I and match it with its corresponding function in List-II. Let's analyze each IC:

1. IC 74198: This is an 8-bit shift register where bits can be shifted in either direction. This matches with "iii. 8 bit shift register".
2. IC 74175: This is a quad D flip-flop. D flip-flops are used to store binary information. This matches with "i. Quad D flip flop".
3. IC 74104: This IC is commonly known as a NOT gate inverting buffer, however, this is a tricky choice as the IC number mentioned might not correspond to common literature IC numbers for buffers or amplifiers, though let's consider it based on given options; it might refer to a line that does not match standard listings. Hence, as per given options, we need to match it with "ii. J K master slave flip flop" assuming an error or mismatch.
4. IC 74132: This is a quad 2-input NAND Schmitt trigger. It matches perfectly with "iv. Quad Schmitt trigger".

To conclude, let's match the list with the correct codes:

Therefore, the correct option is:

a - iii, b - i, c - ii, d - iv

. Note that for IC 74104, given options and standard IC literature might diverge, hence matching based on common opulence in question structure.
