Answer 2

Also we can deduce that carbon bond with 1 degree hydrogen is more stronger than carbon bond with 2 degree hydrogen and 3 degree hydrogen has least bond strength. So to compare their hoc, just compare the number of 1 degree,2 degree and 3 degree hydrogens. More the number of 1 degree hydrogens lesser will be the hoc.

When the number of hydrogens of all types are exactly same, u have to look for other properties like angle strain.

In this case the 4 is the answer..
