A safe, simple, temporary and reliable form of male contraception is–

Correct option is A

Among male contraception methods, condoms are widely accepted for being safe (no side effects), simple (easy to use), temporary (use-as-needed), and reliable when used properly.
​Vasectomy, while safe and effective, is permanent, not temporary.
​Abstinence is 100% effective when practiced consistently but is a behavioral choice, not a device or method.

(a) Use of condom
Condoms are safe, easy to use, provide temporary protection, and are reliable when used correctly. They also prevent STIs.

(b) Vasectomy
Vasectomy is a permanent surgical method, not suitable if temporary contraception is desired.

(c) Abstinence
Abstinence is behavior-based and not a physical contraceptive method; while effective, it's not always practical or consistent.

(d) All of these
Only condoms meet all four criteria; vasectomy isn’t temporary, and abstinence isn’t a clinical method, making this option incorrect.
