Match List I with List II.

List I (Type of Cancer)	List II (Screening Method)
A. Cervical cancer	(I) Mammography
B. Breast cancer	(II) Chest X-ray
C. Lung cancer	(III) PSA
D. Prostate cancer	(IV) PAP smear

(a) a-IV, b-I, c-II, d-III (b) a-II, b-III, c-I, d-IV (c) a-IV, b-II, c-I, d-III (d) a-I, b-II, c-III, d-IV

Correct option is A

The correct matching of cancer types with their screening methods is:
· (a) Cervical cancer → (IV) PAP smear PAP smear test is a screening method for early detection of cervical cancer.
· (b) Breast cancer → (I) Mammography Mammography is an X-ray technique used for breast cancer detection.
· (c) Lung cancer → (II) Chest X-ray Chest X-ray is commonly used for initial lung cancer screening.
· (d) Prostate cancer → (III) PSA Prostate-Specific Antigen (PSA) test helps in detecting prostate cancer.
Explanation of Other Options:
· (b) a-II, b-III, c-I, d-IV – Incorrect, as cervical cancer is detected by PAP smear, not Chest X-ray.
· (c) a-IV, b-II, c-I, d-III – Incorrect, as lung cancer is detected by Chest X-ray, not Mammography.
· (d) a-I, b-II, c-III, d-IV – Incorrect, as breast cancer screening is done by mammography, not Chest X-ray.
