Afatty with the maximum nimber of hydrogen atoms possile is unsatured; is that true?

False.

Explanation:

Fatty acids may be defined as the carboxylic acid that contains the terminal carboxyl group and the hydrocarbon chain. Two types of fatty acid are saturated fatty acids and unsaturated fatty acids.

The unsaturated fatty acids contains double or triple bond in the fatty acids. The hydrogen are removed from the hydrocarbon chain and introduces double and triple bond in the fatty acids. A fatty acid with maximum number of hydrogen atom is saturated.

Thus, the answer is false.

a and b

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
