Answer 1

Hint: We have to know that, the most secure kind of sedation is nearby sedation, an infusion of prescription that numbs a little space of the body where the methodology is being performed. Seldom, a patient will encounter agony or tingling where the medicine was infused.

Complete answer:
We have to know that an anaesthetic, is a drug used to induce anesthesia, ⁠in other words, to result in a temporary loss of sensation or awareness. They may be divided into two broad classes: general anesthetics, which result in a reversible loss of consciousness, and local anesthetics, which cause a reversible loss of sensation for a limited region of the body without necessarily affecting consciousness.
A wide variety of drugs are used in modern anesthetic practice. Many are rarely used outside anesthesiology, but others are used commonly in various fields of healthcare. Combinations of anesthetics are sometimes used for their synergistic and additive therapeutic effects. Adverse effects, however, may also be increased. Anesthetics are distinct from analgesics, which block only sensation of painful stimuli.
Xenon is a strong inward breath sedative with numerous salubrious characteristics; cost has so far relieved the improvement of its utilization for sedation, however late examination has proposed a specialty for xenon, in light of its pharmacokinetic, cardiovascular, neuroprotective, and pain relieving properties.

Therefore, the correct option is (B).

Note:
Since it is a normally happening component, xenon isn't a toxin. It's anything but an occupationally risky gas. It is neither teratogenic nor fetotoxic, as is nitrous oxide; it doesn't add to the exhaustion of stratospheric ozone, as do chlorofluorocarbons and nitrous oxide.
