b. A closed 4-bar chain having 2 revolute and 2 sliding pairs



c. An inversion of the single slider-crank chain



d. A closed 6-bar chain having 6 revolute pairs

Go for option D.

D) A closed 6-bar chain having 6 revolute pairs ✔️

hope it helps u ❤

Answer 2

Option c) An inversion of the single slider-crank chain

• A four link device called the single slider crank chain is used to translate circular rotation into straight line motion. It is an adaptation of the conventional four bar chain. Fixing the cylinder or link 4 in this mechanism results in the inversion.

• When the connecting rod, or coupler, of a slider-crank linkage becomes the ground link, the slider is directly attached to the crank, resulting in slider-crank chain inversion.
• The standard four bar chain has been modified to become a single slider crank chain.
• There are three rotating pairs and one sliding pair in it. In reciprocating steam engine mechanisms, it is typically present. Rotary motion is changed into reciprocating motion and vice versa using this kind of mechanism.
