Digital Integrated Circuit Design

Digital IC design is a procedural interaction that involves converting determinations and highlights into computerized blocks, which are then further transformed into basic circuits. A significant number of the imperatives related with advanced IC plan come from the foundry cycle and innovative restrictions.

Question

in this question, the answer should be C because wwe need to take the total voltage over the total resistance. However, for C to be the correct answer, that means we need to assume that the resistors are in parallel to calculate the total resistance. However, it appears to me that R1 is not parallel to R2 since they do not share the same two nodes? Can you explain why that is?
