Answer:

C.  

Explanation:

Stereoisomers are molecules that have the same molecular formula and with their atoms connected in the same way but pointing in different directions.

<em>cis</em>-Pent-2-ene has formula C₅H₁₀

A. is wrong, because its formula is C₅H₁₂

B. and D. are wrong, because their formulas are C₅H₈

The only option left is C. It has formula C₅H₁₀

C. is a stereoisomer of <em>cis</em>-pent-2-ene, because atoms 1 and 4 are on opposite sides of the double bond.

Think of the C=C bond as a river.

In the <em>cis </em>isomer (top), atoms 1 and 4 are on the same side of the river (zis = zame zide).

In the <em>trans</em> isomer (bottom), atoms 1 and 4 are on opposite sides of the river (trans = across or opposite).

So, C. is a stereoisomer of cis-pent-2-ene.
