List - I | List – II | ||
A. | Malignant tumors | i. | Destroy tumors |
B. | MALT | ii. | . AIDS |
C. | NACO | iii. | Metastasis |
D. | \( \alpha-Interferons\) | iv. | Lymphoid tissue |
The correct matches are:
Malignant tumors are characterized by metastasis (the spread of cancer cells). Thus, A-III.
MALT (Mucosa-associated lymphoid tissue) is a type of lymphoid tissue. Thus, B-IV.
NACO (National AIDS Control Organisation) is related to AIDS. Thus, C-II.
Alpha-interferons are used to destroy tumors (they have anti-cancer properties). Thus, D-I.
Therefore, the correct option is (1): A-III, B-IV, C-II, D-I.

AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
